8 Things You’re Not Considering When Booking a Flight–But Should Be

It’s astounding how many travelers don’t even glance at the make or model of the plane during the booking process. Whether you’re flying domestic or long-haul, not all planes are created equally; if you’re only concerned with seat selection, you’re overlooking a key part of the onboard experience. Newer aircraft are more comfortable, with better-designed cabins, a quieter ride, and modern technology, from power and USB outlets at every seat to upgraded entertainment and lightning-fast wifi. And if you’re an elite flyer, know that certain models are configured with more premium seats, boosting your chances of snagging a coveted upgrade.

Of course, we understand it’s important to gaze outside or effortlessly stretch your legs, but the seat map can reveal a lot more than whether you’ll be by the window or aisle. Use tools like AeroLOPA or SeatMaps (alternatives to the beloved but now defunct SeatGuru) to check the layout and make sure your window seat is actually aligned to a window, and not the dreaded “in-between” wall. If you don’t want to be bothered with noise, traffic, or odors, avoid seating near the galley or lavatories. The bulkhead row offers more legroom but lacks under-seat storage during take-off and landing, so decide if it’s worth the trade-off. Remember that premium economy versus economy cabins can vary wildly between airlines and aircraft types. And if you have a tight connection, select a seat as close to the front of the plane as your fare class will allow so you can deplane quickly.

While you may be apt to think about flight times that align with your vacation schedule, that’s not the only thing you should be thinking about. Booking the first flight of the day requires a brutal early morning wake-up call, but you’ll be statistically less prone to delays, since aircraft are often already positioned at the gate from the night before, and flying early mitigates the “domino effect” of weather and congestion. On the flip side, while booking the last flight of the day allows you to stretch out your precious vacation a little bit longer, delays tend to compound as the day goes on. If yours is cancelled, you’ll have to stay overnight, perhaps at your own expense, depending on the reason.

Airlines regularly sell flights with 40-minute layovers, but this is very risky and isn’t recommended. If you’re returning from an international flight and connecting to another one, keep in mind you’ll have to clear immigration and customs, recheck any luggage, and go through security again, all of which can eat up valuable time—even more so if you don’t have Global Entry, TSA PreCheck, or CLEAR. Also, the time needed to get to your connecting gate might be 5 minutes or 25 minutes. To be safe, aim for at least an hour connection time for a domestic flight (90 minutes is even better) and two hours for an international flight, building in even more buffer if you’re flying later in the day. Finally, remember that if you’ve booked separate tickets through two different airlines, the connecting airline isn’t obligated to help if you miss the connection—a detail that many travelers overlook.

If your flight isn’t nonstop, you’ll have to layover in another airport. Some are well-designed, with intuitive pathways and centralized terminals—or an easy way to get from one to another if they’re not. Others? Not so much. At London Heathrow, for example, changing terminals can take upwards of forty minutes via buses, trains, and re-screening. Terminals at Hartsfield-Jackson Atlanta International Airport (the world’s busiest), Dallas-Fort Worth International Airport, and Denver International Airport are all connected by an efficient train system, but it definitely eats up time. Don’t underestimate the impact of weather, either. Flights connecting through cities like Chicago, Denver, and Boston may be delayed or cancelled in winter because of snow and ice, while flights in Atlanta, Newark, Miami, and Washington, D.C. may be prone to disruptions, including excessive time spent on the tarmac due to frequent summer thunderstorms.

Sure, you might be accustomed to your home airport, but smart travelers shop the region. Booking a flight from an alternate airport might translate to lower fares, better flight times, fewer crowds, cheaper parking, and a more seamless experience all around. At least floating these options is very strategic. Certain airports also have their own logistical quirks and challenges that might impact your journey. San Francisco International Airport, for example, is much more susceptible to fog delays than Oakland International Airport; Fort Lauderdale-Hollywood International Airport is easier to navigate than Miami International Airport, but lacks the latter’s international options; and Ronald Reagan Washington National Airport is convenient for passengers headed into D.C., but often pricier than Washington Dulles International Airport or Baltimore/Washington International Thurgood Marshall Airport. Comparison shop before finalizing your flight.

If you rarely travel, earning points might be a low priority. But if you’re chasing status, or even just trying to rack up enough miles for a flight for your next getaway, then airlines and alliances matter. If you can’t find a suitable flight on your preferred airline, try a partner. Research the members of the three main global airline alliances (OneWorld, SkyTeam, and Star Alliance), and commit to one that makes the most sense for your overall travel plans. While a partner flight might require a connection or slightly higher fare, you’ll at least be accruing points you can use towards future trips and elite status, rather than booking a throwaway flight that doesn’t count. (Basic economy or deeply discounted fares may earn reduced miles or zero elite credit, however, so double-check the fare class.) Even airlines that don’t participate in alliances, like JetBlue, Southwest Airlines, Etihad Airlines, and Emirates, often still maintain valuable partnerships.

It’s tempting to book the shortest flight time, including layovers, and move on. But it’s not quite that simple, and an itinerary that looks fastest on paper often isn’t. It’s important to factor in the trek to the airport (and how you plan on getting there), security wait times, the size and ease of navigating vast terminals, and the final leg into the city after landing. Ride share pickup and dropoff zones are increasingly located further from the airport to reduce congestion and might require a shuttle bus ride, and an airport might be located woefully far from the city center. What looks efficient at first glance can be deceiving. Often, the smarter choice is a slightly longer flight from a closer, more manageable airport that ultimately gets you there sooner—and in a better mood.
