Traveling EWR-YYJ....tried every possible website, but couldn't get a fare in Y below $900, despite starting weeks in advance. Wound up booking EWR-SEA on Continental, then SEA-YYJ on Alaska...2 separate PNRs. Booked hotel, all was well...
except that I booked EWR-SEA on Friday and everything else on Thursday...and found out Thursday morning. Everything was nonrefundable and I was meeting someone else, so a new one-way ticket (from LGA) and a conversion of my round-trip to an expensive one-way was, alas, in order.
I rarely fly Continental, so I still have the voucher for the remainder of my round-trip flight...
