Lost domestic First Class seats due to aircraft swap
Last weekend's schedule change brought an equipment change for me for a flight in August: Flying in Business from Germany into IAD and then on to LGA. I had reserved 2A on the scheduled EMB 170 but the aircraft is now an EMB 145 for both the outbound and the return. I was booked in First (A) but the EMB 145 is a single class aircraft so I guess I'll be in Economy.
I haven't accepted the changes yet.
What are my options now?
