Wifi is free at LCY, but you need to register first these days. Hot meals are served after 5pm. One class on domestic (EDI and GLA). 18D is a good seat as there is only one seat next to you and there is more elbow room. You can usually get off quicker too as long as there are steps at the back of the plane. 1C or 1D are also good, but if you get anyone in 1B or 1E, then elbow room is limited.
