I booked 4 award seats BNA>DEN>BZN 2 weeks ago. BNA>DEN was delayed 3 hours due to mechanical failure. Frontier sent each of us a piddly $30 voucher that must be used within 6 months. I'm on a Summit match for 60 days so I got $50.

$50+$30+$30+30.

I don't have any immediate use for them since Frontier only flies 1 place from BNA. I don't plan to return to Denver before August.

Q1: Is there a trick to extend the expiration?
Q2: Is there a trick to add them together so I can use $140 toward 1 ticket?
Q3: Is there a trick to use them toward a different person than who flew originally?

Thanks,
James
