For those of you too paranoid to register, here's a summary:
American Airlines Inc. restructured its prices to and from its hub operation at Miami International Airport Thursday, lowering some of its most expensive walk-up fares by as much as 85 percent.
... American was seeing passengers shift from Miami’s airport to nearby Fort Lauderdale, where low-cost competitors such as AirTran Airways Inc. and Southwest Airlines Co. had much lower airfares ...
Fares from Dallas Fort Worth International Airport to Miami will drop sharply for last-minute flying. One-way fares bought the day of flying were $910 each way on American yesterday: they’re $240 each way as of today.
