1K GPUs clear into R, regardless of the underlying fare class. If you’re booked on the same reservation, you’ll need R2 before you’ll be able to clear. An M fare is a high fare class, so you should be near the top of the waiting list among people using 1K instruments. However, you’d still be behind anyone using instruments from a Global Services member.
Good luck.

However, if I understood the things correctly, if they open R1, UA will bypass a reservation that needs R2 and upgrade the next waitlisted passenger that is alone.
