I have news for the posters here on FT AA has done the math. The cost savings and additional revenue of heavily banked flights outweigh the costs of dealing with misconnects and re-accommodations. Another thing, get it through your brain-AA doesn't give a rat's behind about the pax that choose AA because it was the cheapest option on a Google search. (Maybe if they take a cc application inflight and get approved.) Nor is management particularly concerned about the stress it puts on airline workers that have to deal with angry, anxious passengers.

Remember, AA (and others) are a credit card mill that uses flying planes as a marketing strategy.

Moreover, those paxs flying for business simply pull out their corporate cc, head to an airport hotel, and get on their laptop and begin to change their schedule. They aren't like the hundreds of paxs I see sleeping in the MIA airport in the early morning because they didn't have the $150+ taxes to spend on a hotel room.
