I fly all airlines as long as they fit my timing and price I am willing to pay. Especially for short haul where I am less flexible than long hauls.
If schedule/price was the same I would probably fly BA since I can get lounge access/seat selection for "free", but I would certainly not mind flying with U2, FR, EW, W6 or any *A or Skyteam carriers.
I am 6'4 and have flown in the middle seat of an FR flight and have paid for seats on Easyjet, Wizzair, AirAsia etc.
On long-hauls I actively prefer OW but I would not hesitate booking any other carrier if the price difference is substantial.
