What are you doing for car rentals? All the majors capitulated on this. I dropped Enterprise when they were the first fold. No there’s no one else to turn to. I suppose the first to backtrack.
Eschew air travel and drive.
Silvercar is a option. There are also now car rentals done by individuals a la AirBnB style called Turo.
I have limited options where I live, Enterprise and Payless only. I switched to Payless a long time ago, since Enterprise service absolutely sucks!
