Very poor signage at London Gatwick airport, I bumped into lots of similarly lost icelandair travellers before finding their check-in. 3 check-in staff for the whole flight meant long queues ~45 mins to check-in. Plane then spent 3 hours sitting on the tarmac at gatwick before departing, so we missed our connection in Reykavik - making for a disastrous trip. Very poor experience. I wouldn't recommend flying with them certainly not with a connection between N.America and continental europe.
