Hi! I'm new to the forums, but I've searched and lurked as a guest for a while. I finally registered because I'm really frustrated with the situation.

I'm trying to book a one-way flight from YHZ to Europe for May next year, but I was preparing to buy a $400 one-way fare last month, and when I checked just now to buy it, it's shot up to a staggering $1500 one-way... the round-trip flight is $1067! It's an Air Canada nonstop to Heathrow.

Why did this happen? I haven't searched it in a while, but I saw it was posted as a good deal ($400 fares available from January to May or so). Surely not THAT many people here booked the fare for that exact day. I saw there's also an Aeroplan mileage deal where you get more miles for flying if you book before December 13th, so could they be bumping the prices up to stop people taking advantage of this somehow?

I need to know some more advanced strategies, clearly. Should I wait until the attention dies down before searching again, so as not to trigger an airfare increase again? At this point, I'll take $500 for that nice nonstop, but there's no way I'm booking a roundtrip just to save $500 off that kind of outrageous one-way.

Thank you for any insight you can provide!
