A: Frontier should have paid you by now. So why hasn’t it?

When the airline canceled your flight, it promised to cover your expenses to get to Cleveland. It gave you 30 days to submit the paperwork and said it would pay you within a month. Maybe it meant to say a month after the initial 30 days?

By the way, I like Frontier’s program for handling flight cancellations. Most airlines offer two terrible choices: a full refund or a flight of its choosing. Frontier’s cancellation recovery program is far more flexible and customer-friendly. But it takes a while to process the refund, which can be frustrating. (This isn’t the only Frontier refund case I’ve advocated recently.)

Under federal regulations, if you made your purchase with a credit card, airlines must forward a credit to your credit card company within seven business days after receiving a complete refund application. For purchases made with cash or checks, airlines must provide a refund within 20 business days.

Frontier appears to have flown past that point a long time ago. Here’s the thing: The government only requires that airlines “forward” your credit to your card. It can take one to two billing cycles before the credit appears on your card. When it comes right down to it, Frontier still might have complied with the law.

Fortunately, you had the airline’s refund promise in writing, and you kept great records. Archiving the airline’s emails and retaining all of your emails to the airline is so important to a successful resolution. Many passengers thoughtlessly delete the emails they receive from an airline, but not you. Nice work!

You could have forwarded your request for a speedy flight reimbursement to one of the Frontier Airlines executive contacts I list on my consumer-advocacy site. I think the airline’s managers would be interested in knowing when they don’t meet their customers’ expectations. But when I asked you about that, you said you’d tried and still weren’t getting anywhere.

I contacted Frontier on your behalf. The airline sent you a check for the full amount of your flight reimbursement.
