BigG, I don't wish to labour the point, but if said person returned from the EU having spent a night or 2 there during the winter, if they left acclimatised then they only have themselves to blame. The argument is often made regarding interpretation vs reality, or more to the point how the ULR variation is applied, so what? definitions are in black and white, I've made the point numerous times to the FDM, fleet and the CP and they have all agreed, so to say I'm due tea and biscuits misses the point, the GCAA approves the variation provided the company complies with the scheme. I'll take my chances TYVM.
