Never Fly These Airlines If You Might Need to Change Your Flight, Data Shows

Although the worst of the pandemic seems to be receding, the fast-changing circumstances of the last two years showed air travelers the importance of flexibility more than ever. Many would no longer dream of booking a trip anywhere without travel insurance. Others simply appreciate airlines' generally more flexible booking policies as a way to protect their investment (and their plans) should they need to make any changes to the itinerary. But not all domestic airlines are equally accommodating—far from it. Read on to learn the two domestic airlines to avoid if you think you might need to cancel your flight.

Allegiant Air and Alaska Airlines are the least flexible domestic airlines.
Noting that searches for "flexible airlines'' have increased by 733% in the last 12 months, the online search tool Next Vacay analyzed domestic airline policies surrounding flexibility and determined the two least flexible among them: Allegiant Air and Alaska Airlines.
The findings came from data points including change fees, restrictions to cancel flights, travel insurance, and refund options. These metrics were assigned scores, which the researchers then added together to come up with rankings.

Allegiant Air still charges change fees.
Unlike many other airlines' new no-fee policies in response to the pandemic, Allegiant charges $25 per person, per flight segment to change a booking. And if you need to cancel more than 24 hours after booking, you will be charged a fee of $75 per passenger, per segment.
Next Vacay notes that Allegiant does offer Trip Flex, which allows passengers to change an itinerary once or even postpone the whole trip without paying the change fees. So if you fly this airline, consider purchasing insurance.

Alaska's no-change-fee policy has limitations.
Alaska Airlines offers no change fees on its main and first-class fares — but not without plenty of restrictions. The airline only allows you to change your flight once before it charges a fee, and it charges a fee of $25 to $50 for same-day changes. Plus, in order to cancel your ticket online and receive a refund or credit, your purchased reservation must meet a range of criteria, including being ticketed using U.S. dollars and being independent from a group booking.
The most flexible domestic airlines include American, Southwest, Delta, and United.
The research also noted the most flexible airlines to fly, which include American, Southwest, Delta, and United.
Southwest Airlines has long been known (and loved) for its flexibility—well before the pandemic—offering no change fees and refundable Anytime and Business Select fares. And if you have to cancel, just do so more than 10 minutes before your flight's scheduled departure time for a refund in the form of travel credit.
And consider that American not only charges no change fees for any domestic, short-haul, and some long-haul international flights, but it also allows travelers to purchase fully refundable tickets. Book your cabin mindfully, though: Even on American, basic economy flight tickets remain non-refundable and non-changeable for travelers.

Experts advise doing your research into an airline's flexibility before booking a flight.
"Whether it's across the globe or closer to home, many passengers are becoming more cautious about the reliability of flights as the travel industry attempts to get back to normal," Next Vacay founder and C.E.O. Naveen Dittakavi, said in a release. "There are many different factors to consider when booking a flight including change fees, refund options, canceling the flight, and travel insurance. Each airline has different specifications so make sure you do your research before booking your ticket to find the best option for the flexibility you're looking for."
