Same destination but totally different travel time
|
This difference may relate to one airline flying over Russian airspace while the other carrier does not do so.

While it probably isn't a factor in this instance, I also notice that in the United States, afternoon/evening flights on the same airline and same route are often >10% longer than morning flights. Airlines get graded for their on-time performance, and if they know afternoon flights are regularly delayed, they lengthen the scheduled flight time, increasing the odds the flight arrives on time.

Often the extra time is on the ground. Later in the day can be more on ground congestion. In the last 20-30-40 years aircraft speed has not changed significantly, but gate to gate is longer time. All due to on ground congestion. |

But airport delays on a 9:30 or 14:05 flight aren't going be anywhere near significant enough to cause the 4:35 difference in timing of these flights. So in this case, yes, it's very likely a flight path difference. |

Keep in mind that the shorter the flight, the more any difference in gate-to-takeoff and landing-to-gate are factored in. Since many flights in the United States are no more than a few hours, and those on-airport delays before takeoff or after landing can be as much as a half hour or so in each case, that's why you can have such variations on shorter flights.
