This has probably been raised somewhere before so treat me gently.

I have been lurking for some time and have finally decided to emerge now that I am on the verge of achieving SM status with an AF flight to Washington on the 9th December. (As an aside - will I be able to use Medallion check in coming back from Washington by AF on the Sunday?)

Anyway, my question is this:

I have read that all fares internally apart from L fares are upgradable. I have just booked a trip for next August LGW-HNL via ATL and LAX. The fare has been booked in Q which is not upgradable internationally but appears to be upgradable internally.

What are my chances of being able to upgrade the internal segments of an international ticket issued completely in Q. It would be great to be able to find a way to upgrade some of this itinerary since particularly on te way back there are two red-eye segments over 2 nights to get back to LGW.

Thanks for helping!
