In any case American plays tough.
Used to work for a Caribbean airline, we used to fly MD80's to Puerto Rico from Trinidad via Barbados and Antigua, when American came on the route they put non-stop 727's from each of those destinations until they made it impossible to compete, as soon as we dropped the route the equipment was changed to an ATR 42 and the price raised. Pretty much the same happened on the Caribbean to Miami route, we had five a day, four MD80's and one L1011, eventually dropped to one a day. Subsequently we shut down and restarted at a smaller scale with most of us having to find new jobs.
American is quite the predator, ask the pilots from South and Central America whos airlines failed.
Such are the hard facts of capitalism.
