I had flights booked with a friday connection in YYZ, landing in LGA at 11 am. They cancelled the 9:30am flight and put me (4 tickets) on the 11:25 flight landing after 1pm. That's too close to shabbos for me. My question is would they honor a connection using another airline? If yes would it only be on partner airlines? I booked these flights using my prestige card @ 1.6 cpp, so as far as AA is concerned its a full revenue flight.
