The Thomas Cook longhaul service has already been upgraded for this summer. Extras such as free soft drinks in all classes and including alcoholic drinks in premium, free IFE headphones, newspapers and entry into VIP lounges when travelling plus and premium among other things. So i expect just the legroom to be increasing as then it will bring them on parr with the rest of the UK holiday airlines. I presume Monarch will follow soon in upgrading their longhaul product, they announced last winter that they were to increase legroom in economy to between 32" and 34" but i don't know what came of this?
