This thread has been interesting for sure! Great opinions and ones I bet no one has considered. I'm now even less confident that ORD will remain a major hub for AA based on the latest posts. Suspect JFK, MIA, DFW and ? LAX will win out. Based on posts on this thread about UA suspect DEN and CLE will slowly fade while UA strengthens in Chicago as its middle of America hub. Too bad FT does not have a map function like they use in elections to have three colors and update on who is dominant where. Would be interesting to see the changes over time!
