Standby being “same day” only means late flights just have empty seats?
I booked a Delta flight for 9 am tomorrow but I want to try to get on a flight at 11:40 pm tonight, otherwise I will have to sleep at the airport. The reason for this is Frontier screwed me over and canceled my flight so now I have to rebook with Delta. With the “same day”-only standby rule instead of being within a 24-hour period, this means you can NEVER get on standby on their late-night flights, and instead they just have empty seats?
