 The federal government getting so many complaints from air travelers, they've only just finished compiling figures from last year. 97,000 complaints, up from about 86,000 the year before, and the most since 2020, when airlines were slow to issue refunds after COVID shut down travel. Delays are part of the problem, affecting around one in five flights in 2023, and again so far this year. But cancellations were low last year, just over 1% of flights and data from FlightAware.
