I was looking up JFK-SFO schedules and noticed that some of the flights have an estimated flight time of nearly 7 hours. Needless to say, almost all of them arrive well before that.
Case in point, UA 7 dep JFK 8:15am, arr SFO 12:02pm. And sure enough, the flight arrives at least 45 minutes earlier.
I understand jetstream, yadda yadda can change on a daily (hourly) basis, but I couldn't help but wonder if UA was doing this to improve their stats? Maybe I'm a closet conspiracy theorist, but just saying ...
