Top 10 Worst Airlines for Customer Service in 2025

When it comes to air travel, some hiccups, like weather-related flight delays and the occasional lost bags, are unavoidable. However, one factor that is within an airline’s control is their customer service. What makes the difference between a positive experience and a negative one usually isn’t how long you waited on the tarmac or whether the in-flight headphones worked, but how you were treated. Good customer service can significantly contribute to making a passenger feel welcomed or smoothing over a difficult situation. Unfortunately, not every airline is able to provide excellent service: the 25 airlines listed here ranked last in customer service in this year’s World’s Best Awards survey.

Overview of Airline Customer Service

From the moment a passenger accesses an airline’s website to the second they retrieve their luggage from baggage claim, there are numerous opportunities for a brand to enhance their customer interface. Conversely, there are just as many ways they can fall short, which the 2015 survey responses highlighted. Several readers noted that a clunky website can be maddening, especially when coupled with inadequate phone support and a hectic boarding system. Other travelers also complained about unhelpful loyalty programs that inspire disloyalty, as they often come with fewer benefits and increased restrictions, making it difficult to use frequent flyer miles.
