Airlines are required to pay customers refunds when a flight is canceled for any reason, but often, in an effort to keep the cash, many airlines offer vouchers or credit for future travel instead of a refund.And when that happens, DOT will be here to make sure that a refund is available and that it's processed as promptly as possible, that we're going to have people's backs when they experience a disruption," Buttigieg told reporters in a news conference over Zoom Monday."Why is it that none of these other airlines have been fined?"But in a statement, Frontier says it will pay just $1 million out of pocket, after having received a $1.2 million goodwill refund credit.The other airlines subject to Monday's enforcement action are:- Air India – $121.5 million in required refunds paid and a $1.4 million penalty• TAP Air Portugal – $126.5 million in required refunds paid and a $1.1 million penalty• Aeromexico – $13.6 million in required refunds paid and a $900,000 penalty• El Al – $61.9 million in required refunds paid and a $900,000 penalty• Avianca – $76.8 million in required refunds paid and a $750,000 penaltyAll of the consent orders are available at www.regulations.gov, docket number DOT-OST-2022-0001."
