Rumours are going around that AA may have some compietition to London, giving AA some compieition. United Airlines wants to transfer thier BOS-LHR flight, ending in two months, to Miami. A fourth carrier cannot enter the Miami-London market until traffic reaches x amount. Apparently, traffic has reached that amount. The United Airlines flight would apparently be a daylight flight, leaving Miami in the morning. But London Heathrow is just the beginning of UAL''s plans for Miami (***uming they are still around), which include RJs to Savannah and Raleigh; mainline to San Juan and Dallas; and the return of services to Port of Spain and Panama City, among others. They want 25% of the market by 2010.
