We are planning for Jan 2009, a round-trip from Toronto to Orlando. Last month the one-way fare from Air Canada website was $168, and now all becomes $257. Just wondering - should I book those tickets at $257 one-way now? This will cost us over $4K (5 passenger + 1 infant). Does the Air fare increase (almost double) because the seats are selling quick? Or it is a periodic thing that seat sale will recur once in a while (I hope)? Should we wait further to wait for last minute deals? Thanks. ...
