Ive just had a look at the list of passengers I have on a flight next week, its a popular destination with almost every LOCO and holiday airline flying there from NCL.
I can see the date the flights were booked and I've looked through to find that most people have booked within last 2 months.... I think that could be the reason, seats on this flight went on sale in 2006, prob for around £5 a seat... the people that have booked in the last 2 months have prob paid around £75 one way.
