None of those LUS hubs are worth a sunbeam.
I definitely like JFK more than PHL, but unfortunately (for us), AA execs have commented on the strength of PHL and CLT due to their profitability
AA has had to compete much more in JFK, LAX, and ORD. As Vasu Raja and his team continue to look at the JFK routes, I think we'll be left with only the profitable ones.
