Hi all!
In September I"m travelling from Budapest to Toronto, and returning from New York to London with British Airways. I have never flew with a Oneworld flight before, and I don't know when I will fly with them next time, but I do not want to lose these miles, so I thought I should enter a ffp.
I'm a Hungarian, my home airport is Budapest. We do not have reward credit card offers, so that does not help to choose. I'm not a business traveller, I travel only for leisure on Economy classes. I prefer to burn my miles for award tickets.

What do you think, which Oneworld program meets my situation the best?
Thanks in advance!
