I've read this entire thread as well as the Lounge Access page at aa.com and I think I'm more dazed and confused now than I was before I started.
This summer, my wife and I are flying in First on AAward tickets (fare code Z) as follows:
MCO > DFW > HNL, returning OGG > LAX > MCO
We don't have status on AA.
Clearly, these flights are not international, so we don't get lounge access that way.
MCO > DFW clearly isn't transcon. How is DFW > HNL treated, since that flight is longer than any literal transcon? Same with OGG > LAX. LAX > MCO sure seems to me like it should be transcon, but it's not on the list of transcon routes on the lounge access page.
And to confuse me even more, I've seen the term "long haul" thrown around this thread a bit. Seems we have at least 3 legs that common sense would consider long haul.
Bottom line: will we have lounge access anywhere along our route?
Thanks to all for the great information provided.
