Well UA and the FAA has made the choice for me since UA has cancelled all of my recent flight attempts with MAX9 stuff so it’s been nice to try out Delta, AA and even some southwest for short stuff. My itinerary this week saw me booked/rebooked on 13 segments for what should have been a 4 segment trip. I cancelled after outbound and return both turned into domestic 30h overnight journeys. Comical rebooking attempts. And also great seeing upgrades cleared into F when my paid J ticket lands me in a middle eco seat on rebooking. And I still technically have GS.
