I looked into this recently, the cheapest by far are Easyjet BUT they go to Stansted which isn't much help, and the times are bad too. British Airways go more often but they aren't cheap.



to be honest, booked far enough in advance the train is much cheaper. 3 hours Newcastle to Kings Cross and then another 2 to Gatwick.

I always use expedia.co.uk or expedia.com because it aggregates flight ticket prices from both budget and standard airlines. Plus I fly from/ to London very frequently.
