Frontier Delayed Flight Compensation In order to make sure that travelers are reimbursed for major disruptions, Frontier Airlines provides delayed flight compensation under certain conditions. Should your Frontier aircraft experience a three-hour or longer delay, you might be qualified for reimbursement for essential costs like food and lodging, as well as refunds or vouchers. The length of the delay, the reason for the delay, and any applicable laws—especially those pertaining to the European Union—all play a role in determining who is eligible for compensation. To get whatever compensation you might be eligible for, it is critical to be aware of your rights and to register a claim as soon as possible.
