Yeah, the taxes I figured. When I've checked JetBlue's Caribbean and South American flights for their point values, it clearly states what the additional taxes are - and I would expect no less when/if they go to the UK.

I was most curious about that "Carrier imposed fee" part. So I'm assuming that you meant the $200 would still count if it was a BA flight but not if it was on AA metal?

Thanks for the clarification!
