This reminds me of a story I read in PCGamer long ago (I tried searching for the article, but I don't even know if it was published online). The author got into their seat for a flight, next to someone with a gaming laptop running a flight simulator. They chatted about video games for a while, and the gamer explains that they like to set up the simulator to play the same flight they are currently taking, and try to take off and land at the same time.
About halfway through the flight, the gamer remarks that the pilot is wrong, and not taking the best route for the flight. The flight sim path and real plane are going in slightly different directions. They try to tell a flight attendant who assures them know "the pilot knows what they're doing." The remaining half of the flight they complained to either the author or other attendants, acting like they knew more than the staff.
They never got to finish their flight-sim though, because the real plane landed 20 minutes ahead of schedule. I guess the pilot did take a different path after all!
