Hi Karfa,
Thanks but I do understand what you have quoted above re AA Exec Plat for domestic US flights. As it was connecting from an international flight in the same ticket, I would say that even if I was flying Economy (so not based on ticketed class), that it is not clearly stated if I should have access or not.
For me the First/Biz rules would be more applicable for passengers without status or a lowly Ruby.
My LAX-HNL flight was in First but since I arrived the previous day on my LHR flight, I was told that it was not eligible. This is what makes me so frustrated about it, to me this seems like it is AA that is stingy in providing/paying the lounge access that's why they have such a rule because basically nearly 99% of their flights would not be meeting it (lounges will most probably be closed for flights leaving just before 6 am) so they can easily deny their members from using the lounges.
So no matter what situation, as an OWE with AA, this is how they avoid paying the lounge fees. I know this is mainly impacting AA members, but it's just such a PITA.
Cheers!
