I "accidentally" stumbled upon it recently, and posted about it here on the VS board.

I have not flown VS upperclass in a number of years, but I always enjoyed it when I did. The service and overall attitude of the airline is (or was at the time) superior to many airlines. And although the massage is not the biggest deal, getting one on a flight is better than not! (As others have noted, you are not guaranteed to get one. Although I am certain the therapist does more than two per flight, there is a chance some will not get one if too many people sign up. You can, however, also get one at the VS clubhouse at LHR.)

I also had my best customer service experience ever with VS. Flying LGW-BOS, I had left my passport at The Ritz. The Ritz found the passport in my room and, knowing that VS had picked me up (complimentary limo service when flying upperclass), called VS. VS was able to put the folks from The Ritz in touch with me in the car (they called the driver's mobile), and I asked them to send it to me at LGW with a motorcycle messenger. When I got to LGW, I told a VS agent at the checkin counter what was going on. He gave me a pass to get into the clubhouse to wait for my passport to arrive. When it finally arrived about 15 minutes before departure, he told me that there was no way I would make the flight, so he told me to come back down to the counter so he could reaccommodate me. When I got there, with about 10 minutes to departure, he radioed to the gate to see if there was any chance I could make my flight. They told his they were about to close the door, and he responded that he was going to try to get me on the flight. He came out from behind the counter, grabbed me by the arm, and raced me through the airport, including through the employee line at security, and got me on the plane just as they were closing the door.
