I realize that because I checked for possible flights. All flights for the next 2 days were sold out. Thus, the decision to rent a car and drive home. One thing I find comical is that I get a text from Delta telling me the flight is cancelled and I should "go on the app and reschedule my flight". When I try to do that, it immediately tells me that I cannot reschedule and I have to call them. Then when I call it tells me that my wait time is approximately "4 hours and 55 minutes". It appears Delta is scheduling so many flights that if anything goes wrong anywhere along the way (weather, crew shortage, etc), then the "dominoes" begin to fall. I have always thought Delta was the "best" airline, but after these last few months, I don't know. We will see how the summer goes.
