It's in the contract. You can use it. They can b1tch and moan all they want. Ofc they're gonna use more than they anticipated. When DL oversells flights by 20 basic economy fares, what do they expect. smh


All you have to do is give yourself two flights that are scheduled to get you to work on time. If you want positive space the second one has to be Delta branded. So your first option can be The School Bus or AA, if you don't make that one, you are entitled to positive space on your DL/DC backup.
