If they cancel your flight all together, their only LEGAL obligation is to give you your money back. Period.
Ummm....not sure about that. I still think they have the responsibility to get you to your destination as planned...I don't think there is a definite "period" at the end of the statement
It has worked for me with every cancellation, or actually flight change. If the airlines initiate a flight change then you have the right to request another alternative at no additional cost.
