I am going to be a weekly commuter for next 4 to 5 months. Delta is the only one with non stop service and charges are so high (lowest is around 600)

I did look at YQG-YUL , you get to save $50 but for that you are flying through Toronto plus need to cross the border etc etc...not worth it.

Any other options ? I looked at buying miles but 25K from Delta is around $900
