We had an almost two hours delay and there was nothing complimentary.

There were a few ‘large’ people on the flight, including myself and my travel companion, who were seated apart. There were also empty seats on the flight and one of the stewards did an exemplary job of rearranging passengers, without being asked, such that me and my companion were together, AND others weren’t ‘crowded’ by other large passengers; moreover, this was all executed without disdain, or condescension. Very well done.
