I have a seat in 1st for this Sunday, 3-March. I want to change to a flight on 5 or 6 March. That is where EF is showing A class, but 3 different agents have stated no A class on those later dates. On EF, it states that discounted 1st on AA should use the award search and NOT flight availability. This is the 1st time I have had with issues of searching for A class on AA in many years. No issues with A class on BA/QR/CX showing on EF and AA also seeing A class.
