This flight from Valencia to Manchester has been one of the best I had. I usually suffer a lot when travelling by plane (you know, sickness, chills, headaches, the whole shebang), but this time I don't know, the pilot had been fantastic because I barely felt the air pressure change during take off and landing. One of the smoothest flights ever - I wish I could always fly with that pilot- whomever they are 😄
