I'm relatively new to trying to get upgrades. So, I need some input on whether or not what I describe below is a common occurrence. My wife and I booked round trip flights (on separate reservations b/c of work) through DL from MSP-ORD in F and from ORD-CDG on AF in W (premium voyageur). I called DL and we were each told that we could pay 30K Skymiles and be moved to business. The agent told me that we were confirmed but we would have to wait for our tx to be re-issued. We would have to call back for seat assignments. I checked the itinerary again today, and my wife was still business on both AF flights, but my AF flights had disappeared! I called DL twice today. The first agent was clueless. I called back and was transferred to someone who "reissues int'l tx" and was told that my wife was still upgraded, but I could only be upgraded on the CDG-ORD segment. Apparently, AF changed the flight's scheduled time by 5 minutes and also decided to change their upgrade availability. They also threatened the Delta agent with canceling my itinerary all together. Can they do that? I stayed on the phone with this agent for almost an hour and refused to get off the phone until he had gotten us confirmed seats on the AF flights. He told us that he had, and our milage accounts were debited for 15 K each since we decided to rough it out in premium voyageur together and go affaires on the way back. My wife received a confirmation of her AF seats. I of course did not get one. What can I do to handle this? (I've already e-mailed DL's customer service.) Are they really the Sky Team? They sure can't seem to work together like one.
