I need to book a flight from manchester to toronto on the 25th of august and returning on the 19th of december.

Right now I'm looking at zoom because it seems to be the cheapest and I flew with them last times and had no problems but right now their being stupid.

If I type in my flight details it comes up with the flight to toronto as £271 but they wont let me book a return, the website says the stays too long and I should book two singles.

So I type in my one way there and suddenly the price has gone up to £331 there and they still dont have a return option.

I really dont understand why I cant book a return? why it's so much more expensive to book? and why wont you let me book two singles whilst were at it?

Serriously the best airline I've ever flown with is air canada, their reliable, their planes are comfortable and they've got good entertainment systems in the seat the only crappy thing is the food, please air canada, I dont want a packet of crisps I've been flying for 12 hours I want a meal.
