Frontier delay compensation
 

I'm very unfamiliar with Frontier. First RT with them this weekend SAN-DEN. Outbound 3 hours late. Inbound looks like will be 2 hours late. Am I able to get anything out of them? Preferably not an eCert because it would be unjust punishment, not compensation.

If the delay was within the airlines control (mechanical issue, lack of crew, etc) then you will get an online voucher as compensation to be used on your next flight. This is pretty much standard procedure on all airlines unless your flight is severely delayed 6+ hours or canceled, in which case you might be reimbursed for meal expenses and a hotel if the airline didn't take care of it at the time.

Pretty much delay compensation is to retain a customer if your not going to be a customer in the future (won't use the voucher) then there is no reason to compensate you.
