The Best and Worst U.S. Airlines in May

Most Customer Complaints

1. United Continental — 291

UAL, which began reporting as a consolidated entity in January, reported the highest number of complaints in May 2012 with a whopping 291. The lion’s share of those complaints related to customer service: including reservations and refunds, as well as mishandled baggage. One explanation: United Continental still is struggling to integrate its operations, and that has caused multiple reservations snafus in recent months.

Runners Up:
U.S. Airways — 109
American — 102

How Other Major Airlines Stack Up:
Delta Air Lines — 91
Spirit Airlines — 79
