I booked a first class ticket through Orbitz from NYC-DFW on Delta. I just checked in, and they gave me an economy seat, saying that I only bought a fare class that was upgradable, not an actual first class ticket. I was checked in with a confirmed first seat, but apparently there was an equipment change to a smaller first class. I just noticed that Orbitz booked me into Fare code A, which after checking, is just an upgradable coach fare, and has leeway for them in case of change of equipment to leave me in economy, even though i was confirmed on the original equipment. I assume I am going after Orbitz for selling me an "upgradable" ticket as a first class ticket, which is not really a first class ticket, even though they claim that it should have been a first class ticket. Any thoughts/ideas?
