Connecting on Award ATH-YUL-BOS (short)
I'm considering booking UA mileage award flights for daughter, husband, and kids for an AC TATL flight (ATH-YUL) arriving Montreal at 3:00pm connecting to an AC YUL-BOS flight at 4:25. Is that doable? There's another flight about 2 hours later but not available as award. If they miss the 4:25pm flight, will AC book them on the later flight assuming there are any open seats? Otherwise, I can book them on connecting flights though EWR which will get them to BOS about 11pm....not fun after a TATL flight.
