if you can go from newcastle its only 'a3115 return inc. taxes!!! 22/6 1 week. thats on airflights! day time flights aswell, just a bit of a trip from luton - although its worth it - lovely people up here!
you do get better deals if you book in advance, the later it is the dearer it is thesedays! i think the airlines got wise to everyone leaving the bookings until last minute to get the best deals.
try travelsupermarket.com for 'single tickets', thats pretty good!
