I need four return tickets Perth-Toronto-Perth.
But they can be at any time from July-September, and the trip duration is flexible also, though 2-3 weeks is what I want.
Most travel sites (Zuji, Kayak etc) make you start by putting in a departure and return date (maybe with a plus-or-minus 3 days), and presumably if there is a flight $2000 cheaper on the very next day, then you just won't see it.
So what I want is a travel site that lets me say "Perth to YYZ anytime in July/Aug/Sep for anywhere from 14-21 days".
I looked at the Travel FAQ here (on OzBargain) and it led me to "adioso.com". This allowed me to specify a MONTH and trip duration of "about 2 weeks" or "about 3 weeks", and using this I found some Delta tickets for about $1270 return. But at the same time I found some Cathay Pacific tickets for $1333, which are much better for me because the Cathay flights are single-stop and so end up about 7 hours shorter than the Delta flight. And the Cathay ones avoid LAX which is always a plus.
But now I've lost the Cathay tickets, and can't remember the exact search I used (even for adioso, you still have to specify some things)
Does anyone here know of any other site that has similar or better functionality?
Skyscanner will let you select an entire month and show you the cheapest return ticket, you could just perform separate searches for July, Aug and Sept?
