Flew from Manchester to New York flight good adequate leg room. Then flew new York to Washington flight good. Last flight Dulles to Dublin smaller plane leg room minimal. Throughout all flights flight attendants helpful and friendly. Security staff at Dulles airport not very helpful. I am slightly disabled and walk with a stick. I was asked to remove my trainers. When I asked was there a chair I was told no. There was a chair the other side of X-ray machine. A friend needed to untie laces because stick had already gone through. No consistency people on other belts let through with shoes on.
