I know we all feel good about saying that we will sue if the airlines don't give us what we want, but I agree with the side of this issue that says AA isn't doing anything wrong. People - you are getting something for nothing! You agreed to pay $400 for your ticket from LAX-LGA or LAX-LHR-SIN-LGA for $200. The fact that we get anything else is a bonus. I didn't see this much venom when some airlines discounted miles for deeply discounted fares. (or maybe I was watching football) They give six months notice; plan your travel. I'm planning a trip during the summer for my family to the EU. If UA said that the intl awards were going up, I would book that trip very VERY quickly. If I couldn't get a single seat in the next six months, that would be another story. If AA said that they would discontinue the program completely and all points were null, then there could be some legal ramifications regardless of what they put in the T&C's. Yes, there is unenforceable clauses, but that's a topic for a Saturday seminar.
Wake up people, we are in a different world now. DO we really want to go back to a regulated (gasp!!) airline travel environment? As soon as you say "the government should step in" that what it's getting to. I don't think so. I'd like to still be able to get a free domestic 25K mile ticket for one trip to Asia, but it look like that won't happen.
