Why can’t I use this United Airlines voucher?

A: I’m very sorry to hear about your loss. United Airlines should have quickly sent a refund to your agency, which should have returned your money, not vouchers. Why money? Because that’s what should happen when an airline cancels a flight. At least, that’s what the Department of Transportation says.
