What are your rights when an Airline mucks you around in the US

[markis10]

There have been recent changes in the LOTFAP in regards to passenger rights, here is a good summary:

Airline inconveniences and fliers' rights

[h=4]BUMPING[/h] Scenario The airline sells more fares than it has seats on your domestic flight. Someone's got to stay behind.
Recourse You are entitled to as much as $650 cash compensation if the airline rebooks you to arrive two to four hours after your original arrival time; more than four hours, up to $1,300. You're entitled to receive cash. Do not accept a travel voucher; they often come with restrictions and extra hassle.

That $650/$1300 is the maximum. Up to that it's based on the fare paid (Double/Quadruple).

Of course that introduces a grey area in relation to multi-segment itineraries.
