Confused

So I am looking at varying our holiday next year (normally Vegas) and heading to Canada. We normally fly from Manchester. Is there anyway to fly Manchester to lhr then on to Toronto using the reward voucher. I have about 90k miles at the moment, but it looks like I may be better keeping my points and spending cash with the reward voucher. We would be looking autumn next year so dummy booking isn't an option so far. Is the man to Toronto an option?

I would have thought it’s possible but flying MAN-JFK-YYZ. I appreciate that’s two lots of immigration in quick succession.

In case you’re not aware, there are direct options from MAN with other carriers - Air Canada & Air Transat.

Ah. But I have a 2 for 1 voucher thingy
