Yeah, that's what I saw; but the agent indicated that I wouldn't be able to even book economy on that AR flight either. Now, this makes things stranger. Guess I'll be giving Delta a call today from the office.
Separate from this; how does one book AR's Club Economy class with a Delta? I was under the impression that was their business/first class, and I would think there would be a way to book it, no? If I cant get it on that AEP-GRU segment, I'd love to know if I can expect to be able to book it for my planned side trip to USH.
