I flew with thomsons and it was 20kg and 5kg hand luggage, you can pay something like £30 for an extra 10Kg with thomsons, unless you are family not sure you would need an extra 10Kg... most holiday firms offer excess baggage at 5kg, thomsons changed theirs this year to 10kg
oh and make sure u take something for yours knees if your long legged!!!, no leg room, every time the person put they seat back or got up and sat down ooh break your knee caps!!!!
thanks for all the advice guys. i go on the 23 feb and cant wait. i am tall so may have to take some padding for the knees if there isnt alot of leg room with thomsons. some thing to look forward to.
