Didn't like anything from this flight starting with the lady at the counter. Nasty attitude.

The plane had to load and unload passengers not through a jet way but out on the tarmac at Heathrow. The steps were steep. We weren't expecting to have to carry our luggage up and down stairs.

The crew was wonderful. Service was great. The discomfort came from the passenger behind me kicking the seat.
