Thanks for the NWA info Alex - I found $448 RT from Ontario with just one stop in Minneapolis (beats Delta's ONT - Atlannta - St. Lous - Boston - Montreal schedule) and it's about 7 hours 42 minutes instead of 10+ hours one way.
Also....for any So. Californians....we usually fly out of Ontario because Palm Springs is too expensive (try an extra $200 per ticket) and LAX is....well, anyone who has flown LAX knows what a pain in the ass it is. BUT...for those who don't mind a little side trip to Vegas they have tickets there starting at $364 RT (same deal to Minneapolis and on into Montreal straight). Save a little money....spend a couple hours in Vegas...talk about your win-win situations!
Thanks for all the tips guys - this really helps.
