In the United States, almost all carriers have a clause in their contract of carriage that says the airline will rebook you on another airline to get you to your destination if your flight is cancelled or has a major delay. The language is pretty standard, right down to the clause number (clause 240), although some airlines use a different number. F9
's is at http://www.frontierairlines.com/pdf/Contract_of_Carriage.pdf.
While there is no law requiring this in the United States, congress considered a law after several people were stranded on airplanes for several hours (NW and UA
in particular) without any compensation. To prevent the law from being passed, the airlines voluntarily implamented what the law would have required. The one big thing is that the airline must have an interline agreement with the other airline. Most airlines have a couple partners, with WN being the biggest exception to this.
I've seen airlines rebook people on other airlines if there is a problem. Once, I was flying NW
. My DEN
flight was delayed, and I missed my MSP
flight. They booked me on the next flight on NW
, while others were booked on NW
, and then AA
. I also saw F9
offer overbooked passengers a routing on CO
when the DEN
flight was oversold.
