I don't really get the complaints about the vouchers. Every airline offers are good for any ticket directly sold by them...(there are specific ticket classes that cannot be booked directly with the airline that will not be allowed, but a normal person cannot get those except through vacation packages). This only comes up as a problem if you buy a vacation package through the airline and want to use the voucher to pay for the tickets. Usually you'll end up having to pay more in order to bump the ticket class up in that case, but not $800 for a short haul flight.
