How ironic.
One receives vouchers in return for voluntarily inconvenience to help Delta Air Lines on an overbooked flight.
In return for the inconvenience experienced at the time of the issue of the voucher, one is “rewarded” with additional inconvenience to redeem said voucher.
I suppose in most cases it is worth 200 Delta Dollars (there is a reason why they are called Delta Dollars, I suppose, instead of simply Dollars), as I have voluntarily accepted vouchers in exchange for being bumped off of an overbooked flight, but Delta Air Lines should relax some — if not all — of the rules regarding redemption of vouchers which are supposed to reward passengers for assisting Delta Air Lines on overbooked flights.
I remember the days when the vouchers were for a free flight round-trip anywhere Delta Air Lines in the continental United States and Canada, but I suppose vouchers are not immune to being “enhanced”...
