just booked a YUL trip again for next week... $1072 roundtrip BOS-YUL. my return is in seven days, which means i got a $300 cheaper fare in that direction..
they're not even all jets any more! air canada is selling $700 one-way tickets on dash-8's between BOS and YUL.
i booked an AC ticket rather than a UA ticket. saving $3 each way for not checking a bag was nice, i guess, but it's also a lot easier to do same day changes coming home on AC metal if you're on an AC ticket...
