I'll try to make a long story (2 hrs on the phone) short... My wife and I planned to fly KIX-SFO-LHR with only a 2-hour stopover in SFO. I've done this twice before in the pre-merger days on UA, and was able to use one GPU in each direction. This time, it took two hours on the phone, with the agent checking in with the fare desk multiple times. They said that the fares from KIX-SFO, and SFO-LHR were not "combinable" but finally they finally did find a fare for a little over $3000/RT. They warned me, however, that any change in the itinerary would result in the fare getting bumped up to over $10,000. I said "Fine. Now I need the same itinerary for my wife." Agent: "Oh, I'm sorry. We only have one fare available at that rate." Arggh! So, I went online, and easily booked two W class fares from KIX to SFO and SFO-LHR, using a GPU for KIX<>SFO and upgraded with miles for SFO-LHR for the both of us at a cost of almost $4000 for each person. So why aren't two W-class fares combinable?? I can only guess that they are trying to reduce the value of the GPUs. Has anyone else had a similar experience?
