I believe the booking window they monitor for such routes as BUD, KRW, CHC is like 7-10 months out. I guess they weren’t seeing strong demand on those routes, and I’m not surprised. Not too many people are going to book a fancy EU/NZ vacation for next summer with the uncertainty around international travel as it stands today. Would you?
However if there’s a miracle vaccine and things snap back to normal early next year, AA can still serve those destinations via LHR/MAD/BCN. Not ideal but hey, what is in today’s world? They can always add the non stops in 2022 if the demand returns.
In other news, AA just brought back LAX-HND and about 8 other Caribbean routes out of MIA and CLT. Hope it’s the right move.
