Delta flies where I need/want to fly non-stop, and with KL/AF, one stop to most of the world I can currently fly to, and with KE, the other part of the world that hopefully in the future I can fly to again. I haven't had one bad experience/irrop on the 52 flights on dl/kl/af I've been on since the pandemic began. Airplane food is trivial to me, as it's never something I looked forward to prior to covid-19. Upgrade me to first domestically, and I'm happy.
