Need help from the experts. Due to circumstances beyond my control I will be 3 or 4 segments short for the promo. Found some good fares to the U.S but no availability. Within Canada I am getting low fares but in N or T booking class. When I check in L the fares double or triple. Any help would be much appreciatied. Thinking of the weekend of Dec 8th and 9th.

Thanks in advance.

Biggles.
