Airline ticket prices went up by 25% last year, outpacing inflation. Cost isn’t all that matters when picking what company to fly with, though; choosing the wrong airline has the potential to take even more from us. For instance, 7 animals died during air transportation in 2022, and two major U.S. airlines had at least one pet fatality.

While critical to consider, such factors often fly under the radar due to our focus on price. But finding the most affordable airfare is now quite easy for anyone with an internet connection, so this report examines those other, overlooked aspects of air travel to help consumers make more-informed decisions.

WalletHub compared the 9 largest U.S. airlines, plus two regional carriers, across 14 important metrics. They range from cancellation and delay rates to baggage mishaps and in-flight comfort. We also considered costs in relation to in-flight amenities for the sake of fairness. For example, it wouldn’t be right to penalize an airline that charges for drinks if its tickets are far cheaper than those from an airline with free in-flight refreshments.
