Our flight to London was delayed an hour but the flight itself was good. The captain had a wonderful dry British wit. The flight attendants seemed a little aggravated when passengers were getting antsy as a result of needing to use the restroom, but that wasn't the passengers' fault. They just thought they would have been airborne an hour prior and that expectation (which they paid for) wasn't being met. A hard place to be for both crew and passenger.
