well, I for one am happy to know this because that was one of options to connect to Bali. Thanks for letting us know even at your own expense. I'd be pretty unhappy, too. I'd probably give them the boarding pass back, ask what's it about, then layover one nite just to avoid coach. Sorry you got the shaft. That really stinks!
It has to be an issue about all those empty seats in coach for balance. I flew the 747 to DTW from NRT this spring and sat up top, but it was the old config--reclined seats, no beds. It was very cool, nonetheless.
