Hello,

I normally fly VS out of Heathrow, but it looks like there is quite a bit of BA in my future due to a few upcoming business trips to destinations where VS does not fly.

I'm trying to decide which Oneworld programme I should join. I've read that BA has the world's least generous FF programme and that it takes forever to earn enough miles for an upgrade, much less a free flight -- is this true? I have a few miles with AA but not enough to make it a clear choice.

My main priorities are:
A) Mileage thresholds for FF seats
B) Being able to get FF credit for discount economy class
C) Ability to use miles to upgrade on BA

I fly primarily UK-US and UK-Africa routes.

Cheers,
Julian
