I found out that when, for example, you make a flight from EDDF to FAOR. It normally takes 10 hours, but you don’t have time the entire time so you use autopilot+. You continue it, then get off again, continue it, get off again and so on. You will get more xp per cycle. I made this cycle 3 times and immediately got 12000 xp for a flight that only flown 7 hours till now 12000 xp are actually only for 16 or 17 hours flight I think but if you repeat this cycle many many times you can theoretically get over 1 million xp in a less than a day
Here is what I got for 3 cycles
Before the flight I had 489.000 xp
