So far this year, around 18% of flights have been delayed and slightly more than 5% have been canceled, according to data (ending February 2022) from the U.S. Department of Transpiration's Bureau of Transportation Statistics (BTS). A flight was considered delayed if it takes off or arrives 15 minutes or more after the scheduled time. When it comes to dealing with flight delays and cancellations, or other situations that could throw a wrench in your travel plans, it's important to know who you're flying with and the airline's reputation. If something were to go awry, these situations — especially flight delays and cancellations — could have a costly impact and is where travel insurance might help. This year is shaping up to be one that stands out for canceled flights, a dubious distinction it would share with 2014, which saw 6% of flights canceled while nearly a quarter of flights were delayed, according to BTS data. The above slideshow ranks major airlines based on reliability, according to WalletHub, which factored in the frequency of cancelations, delays, mishandled luggage and denied boardings to build the list.
