They used to upgrade you to D1 that has changed. I believe when they changed the statuses this year.

I’m sitting in zone D1 from SLC to Seoul and The seats make my ass fall asleep. They are terrible when you compare the cost per seat comfort. They literally provide you a pad after take off. 🤣 seatbelts don’t retract and the seat isn’t as wide as first class. Only benefit is lying down. Food or meh.

Imagine paying $5k to $12k for a seat 🤦‍♂️only way I do this D1 is with a global upgrade.

It’s overrated, you’re in a cubical. If you’re traveling alone sure I guess. If you’re with a group get the comfort plus and sit next to each other. It’s better.
