### FAQ

#### Is a PMP certification worth it?

A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations.

#### What are the best certifications for project managers?

The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation.

#### How does PMI support career growth for professionals?

PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers.

#### What is the PMBOK® Guide?

The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery.

#### How is AI changing project management?

AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment.  PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes.

#### What are the most important skills for a project manager?

Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates.


#### How can I get involved with the PMI community?

Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections.

#### What is the difference between PMP and CAPM?

The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification.

#### How does PMI support social impact?
PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world.

Apr 22, 2015 3:36 PM UTC

Online flight search services are big business, as more of us turn to computers and smartphones for travel planning. Last year, [40 percent of Americans](http://venturebeat.com/2014/09/19/travel-bookings-by-mobile-devices-in-u-s-now-at-40-percent-and-growing-report/) booked flights, hotels, cruises and other holidays on their phones and tablets, a statistic based on 300 million bookings worth $150 billion, while [the Economist](http://www.economist.com/news/business/21604598-market-booking-travel-online-rapidly-consolidating-sun-sea-and-surfing) reckons that online bookings account for 43% of total travel sales.

The options are growing. Google recently overhauled its flight aggregator service, [Google Flights](http://www.google.com/flights), with the addition of [money-saving features](http://www.techlicious.com/blog/google-flights-routehappy-in-flight-wi-fi-data/) posing serious competition to established heavyweights such as Kayak and Skyscanner. Then there are newer, design-led services like Momondo or Hipmunk, which offer filters by price as well as convenience.

## Are you really getting the best deals?

We’re spoiled for choice when it comes to services that search other services for the best deals — but despite the thousands of results these services manage to turn up, you may not necessarily be getting the cheapest deal or even the fare advertised.

Buyer beware: Most fares found by these flight search engines don’t include the baggage fees charged by some low-cost airlines as well as United and Delta. In some cases, they don’t include fuel taxes and other surcharges.

Nor does every airline shows up in these metasearches, says Matt van der Rohe, an online travel expert with travel concierge service [Flightfox](https://flightfox.com/). For example, Southwest Airlines does not put its fares on metasearch sites, and UK-based budget airline Ryanair saves its cheapest fares for its own site.

We picked six of the top-rated flight aggregator services and compared prices for 10 flights over a week in June, from domestic flights including New York to Los Angeles, Seattle, Las Vegas and Austin, and international flights from New York to Toronto, Sydney, Paris, Rio de Janeiro and Hong Kong.

## Which flight search service is best for you?

### Kayak

_Available for iOS, Android, Windows and Kindle devices._

The granddaddy of flight aggregator search sites, [Kayak](http://www.kayak.com/), was recently redesigned to streamline its search interface. Kayak now offers tons of ways to filter your search, including an intuitive slider system for adjusting approximate takeoff times and options to show or hide redeye flights, view flights with Wi-Fi only and see “hacker fares,” where different legs of a journey are purchased separately. Also handy is the ability to adjust the maximum layover you’re willing to bear.

A new price trend graph offers advice on whether flight prices are likely to go up or down, giving you as much peace of mind as one might be able to expect, while the fee calculator can add credit card and check-in luggage fees to the posted fares. If you search for flight and hotel packages, Kayak can also tell you how much you’ll save by booking the two together over booking them separately.


**Bottom line:** Kayak almost always found cheaper fares than any the flight services in this list (or at least within a few dollars of the cheapest). On the NYC-Cancun flight, it scored the cheapest flight by far at $398 (compared to $466 and up on other sites), thanks to being the only site that accessed fares from Aeromexico. Its fee calculator for credit card and luggage fees also means you’re most likely to click through to a posted fare.

### Skyscanner

_Available for Android, iOS, Windows, Kindle and, BlackBerry devices._

[Skyscanner](http://www.skyscanner.com/) is the other search giant offers similar results to Kayak in an equally straightforward interface. It provides a couple of easy tools for filtering out particular features like takeoff times and number of stops. Clicking on a particular flight shows exactly how long the layover is. However, there is little additional information given about flights; for example, there’s no obvious indicator for overly long flights (as most of the other services in this list offer), nor does Skyscanner show in-flight amenities like Wi-Fi.


**Bottom line:** Skyscanner tended to turn up domestic fares that were roughly the same as Kayak’s, give or take $5 to $10, for flights that cost $300 to $500\. It matched the other services for rates to Paris and Sydney but missed finding the cheapest flights to Hong Kong and Rio (despite finding the same airlines).

### SeatGuru

_Available for Android and iOS devices._

[SeatGuru](http://www.seatguru.com/) is an airplane seat plan and flight search site, owned by TripAdvisor, offers many intuitive filters for your travel hunt in a simple, quick-to-use interface. Results are displayed in a clean, comprehensive style that allows you to sort based on price and direct flights, filter to “avoid early flights” and weed out pre-8 a.m. departures, and apply a “best value” selector calculated by flight time, cost and number of stops.


Each result displays various flight amenities, such as Wi-Fi, the option to purchase additional legroom and whether the seat pitch is average or good. SeatGuru uses the Expedia database for hotel packages, so you’ll see the odd, ad-like hotel suggestion pop up in the middle of your search results to show you how much you’d save by booking a stay along with your flight.

**Bottom line:** SeatGuru came up with comparable fares for international routes. For domestic flights, it sometimes turned up the cheapest fares found by the other services (give or take $5), but it was sometimes (Cancun, Austin) pricier by about 10 percent. Its filters for search results make choosing a flight easier than those on Kayak and Skyscanner.

### Hipmunk

_Available for Android and iOS devices._

The home page of [Hipmunk](http://www.hipmunk.com/) consists of a search box asking where you want to go and when. The real design beauty of Hipmunk is its “agony” rating of the ensuing results. Whereas older sites such as Kayak and Skyscanner leave analyzing its thousands of results to you, the hunter, Hipmunk orders flights by how long they take. Layovers usually push up the agony factor. You can also order flights by price and takeoff or landing times.


When booking flights, the outgoing and return legs are chosen separately, making it much easier to pick the times you want, rather than plowing through the endless list of flight combinations employed by many other sites. Any extra cost incurred by particular flight times is displayed next to the flight, so you can easily scroll to the choices that don’t cost extra.

**Bottom line:** Hipmunk tended to find the cheapest international fares (that is, as cheap or cheaper than the other services in this list) and around the same prices on domestic fares.

### Momondo

_Available for Android, iOS and BlackBerry devices._

Momondo is a flight, hotel and car rental booking site that has a brilliantly fast search with intuitive controls. Flights can be ordered by price, speed or “best,” based on an algorithm computing flight duration and cost. There are extra checkboxes for filtering by airline, departure or arrival times and, uniquely, by frequent flier alliances, which is handy if you’re savvy about air miles. Two bar graphs show the rise and fall in price of both outgoing and return flights.


If you can’t quite decide where to go on your next vacation, hit the Trip Finder to find destinations based on what you want to do (city break, shopping, the beach), when you want to do it, a rough area to head for and, most usefully, the budget you have available.

**Bottom line:** Momondo has excellent coverage of online travel services and airlines and, in our test, it turned up the cheapest flights (either the same cost as the cheapest, or about 2 percent to 4 percent cheaper on both domestic and international). Choosing flights is made easy by a clever set of filters for airlines, flight times and convenience, while the bar graph fare calendar helps flexible travelers pick the cheapest dates.

### Google Flights

With the world’s most-used search engine backing it, you’d expect [Google Flights](http://www.google.com/flights) to clock a blistering search time, and it does. The interface is reassuringly clean, minimal and Google-y, returning results in about a second — much faster than every other service. At the top of each results list is a tip suggesting how you can fly for less; for example, we could have saved $25 on our $425 New York-LA flight by shifting the week-long trip forward by a day. This change is bookable by simply clicking on the tip. Otherwise, found flights are filtered with “best” flights first, based on flight times and flight duration balanced against cost; it doesn’t always choose the direct or cheapest routes.


Flights can be booked as separate legs with different companies. You can save your itinerary for price alerts on [Google Now](http://www.techlicious.com/blog/google-now-nearby-shopping-alerts/) or share it via email with your travel buddies.

**Bottom line:** Google Flights scored the same fares for most domestic flights and the longest flight (NY-Sydney), but it turned up pricier flights for Paris, Rio and Hong Kong.

## When travel agents come in

For straightforward flights — fly there, come back — most of us can quite easily get the best deals simply by hitting up one flight aggregator site or, in many cases, an airline that flies where we want to go.

But when it comes complex routes like a transcontinental trip in January from New York to Sydney with stops in Singapore and Bangkok, you’re unlikely to get the best price (or airline selection) by simply punching in a multi-city trip and booking it all through an aggregator site. For example, the low-cost airline Scoot that flies direct from Sydney to Singapore didn’t turn up as an option on this route (despite being listed on at least some of the other search engines).


This type of itinerary is where new-gen travel services such as Flightfox make their coin. Unlike traditional travel agents, Flightfox does not take a commission on flight sales. Instead, the company charges customers a flat fee for a human agent to hunt down the best fare for a given itinerary and then send the customer the link to book themselves.

Van der Rohe says he mostly uses the same sites as we might, as well as a few accounts that send extra information about fare availabilities. “What we have is a knowledge of routes, fare rules and loopholes that can lower the cost of itineraries beyond what you might see at first in flight search engines,” he says. (He won’t divulge what these loopholes are, exactly.) He did, however, share a few tips for searching with flight aggregator apps at home.

“There’s a lot to be said for brute force,” he says. Search as many flight combinations, airlines and routes as you can think of across many different sites.


If a flight aggregator site isn’t giving you the price you want, look up an airport’s Wikipedia page and see which airlines fly to it. Then search for fares on these airlines’ pages.

Comb forums such as [FlyerTalk](http://www.flyertalk.com/) and [MilePoint](https://milepoint.com/), which are bases for travelers to share flights and routes and deals.

Try searching on different days of the week. “Every day and every flight there are certain seats and certain fares, which change all the time,” van der Rohe says. (In the two days since the flights for this article was researched, some fares have dropped.)

If you’re very eager (or a travel manager),subscribe to [Expert Flyer](http://www.expertflyer.com/), a site aimed at frequent flyers that sends alerts when a particular seat on a flight becomes available. “Sometimes seats right next to each other are different fares,” says van der Rohe.

As for when to book to score those cheapest fares, Kayak research based on a year’s worth of search data found optimal days to leave and return and an optimal window during which to make your booking. For example, you’re likely to find [the best airfares to Europe](http://www.kayak.com/travelhacker/global/europe) from the United States and Canada by departing on a Wednesday and returning on a Tuesday and booking six months in advance. In contrast, [an Asia trip](http://www.kayak.com/travelhacker/global/asia) is best booked five weeks in advance, departing and returning on Wednesdays.


At the end of the day, finding the cheapest airfare is best accomplished by grunt work interspersed with anxiety over whether flights are going to get any cheaper. That’s why van der Rohe advises customers that if they see a price they’re happy with, they may as well just book it.
