Due to (I think) equipment failure Because of snow in Washington DC, last night’s IAD-LHR flight was cancelled, which meant that United was forced to cancel an LHR-LAX flight. They tried to accomodate as many of the LAX passengers as possible on the LHR-SFO flight, which meant that when Kate and I went to board our flight home, we were upgraded to Business class. This made the nearly-11-hour trip much more enjoyable….
