Frontier cancels paid ticket over credit review, demands rebooking fee (onemileatatime.com)

Frontier Airlines canceled a paid ticket booked by a colleague on October 7, 2026, for a $189 flight from Austin to Denver, citing a "credit review" about 55 hours later. The credit card had already been charged, and rebooking online now costs nearly double the original fare. Frontier's chat support said the fraud review decision couldn't be overridden and suggested visiting an airport with a government ID for a new booking, which would incur a fee if done through an agent.
