I know Virgin does special offers, and i have paid £2003 for 3 ad and 2 children. Last year, same period it was £1700. How much do the offers vary and when is the best time to buy? Too late for this time but not for the next booking!
How long is a piece of string?..... the problem is nobody knows for sure when VS will have special offers/fares available etc. Obviously you can pretty much say the busy times (like school holidays ext) no sale fares will be offered but the quieter periods there is more chance.
