I and 3 others recently flew with j2, outbound was AE, we was lucky, as we have contacts at LBA we got row 12 been the bulk head exit rows. On the return leg we had to go on AI, and a slot out of PMI in 35 oC heat, meant we had to sit with no personal aircon, just the crap aircon blown around the a/c which was about as much use as a chocolate fire guard. We are all average height and size and was sat there with our knees youching the seat in front. Ive travelled with ryanair before and muct say the sead comfort and leg room is far better than what is offered on j2.
