I have flown VS Upper Class 3 times this year, & only on one occasion was I impressed.
The VS crew are really awful - no attention to the finer details towards their premium passenger. I have always claimed that VS are just a glorified charter airline.
The seat on both the A340-600 & 744 are truly uncomfortable, and offer much less space when compared to other airlines offering similar service for roughly the same price.
Within the last 12 months, I have also travelled with SQ & BA, 1st and business at least 10-15 times. Never a problem with either carrier. Service is so much slicker and promt. When i'm spending near GBP4000 per ticket, I expect a lot more than what I get when I fly with VS - which usually equates to a very unfriendly flight.
To answer the qu at the top of this thread, don't waste your money mate - fly with BA or someone else & save yourself a lot of hassle.
