I'm new to this board. I recently booked a trip from IAH to SVO through CDG. On bad advice from my travel agent who said I could use my sky miles to upgrade on Air France, I told her to book the ticket. I have since learned that I cannot use my Delta miles to upgrade on AF! My wife and I are going to Russia to pick up our adopted daughter and we would like to be able to upgrade our return flight so we can be more comfortable after a very trying week. I would be willing to trade my Delta and NW miles (about 100,000) in exchange for three business class upgrades on AF. Is this even possible?
