I have the good fortune...?... to travel on this route at least once a month and have done for the last three years (the worst has been 3 times in one month!) This flight is the most unpredictable I've ever been on. Sometimes it's from a gate, sometimes bussed, sometimes on time (I faint at that point) sometimes late, sometimes great service, sometimes mixed, sometimes on a 787-9 (rarely now) sometimes on a 777-200 or it could be the 300 variant.
