Don't forget AA helping kill companies like Braniff, People's Express, and Legends. Good companies attack weak companies, protect their home turf, and take advantage of opportunities made possible by others companies failures.
Fornaro and crew spent alot of time studying the MKE market as they made their takeover attempt. They saw a weakness and attacked last summer with 30 flights a day with the fuel efficient 737 platform in Midwests core markets. No different than Delta sensing Airtran was weak late last summer and Richard Anderson ratcheting up the pressure on Airtran by not reducing capacity in competing markets. Luckily for Airtran, fuel prices dropped as hard and quick as they spiked or things might be very different in the ATL this spring.
