Dear sages,

There's a 3 class 777 flying LAX-IAD. (Not sure if a one-off, or just the day I want to fly).

I have a ticket on hold that booked into A class (but it's an econ fare with an upgrade). Neither UAL.com nor the agent is able to assign a seat, though there are many available on the generic seat map).

Questions:

1) Does "A" map into business or first?
2) If it maps info F, but I somehow end up in C - will I be able to refund before the flight?


Thanks in advance!
