How long can A plane stay up in the air?

Any plane. How much fuel does it carry, and for how many hours can it travel in the air? I've heard 20 hours, but I have no clue if it's true or not. I'm pretty sure It's more then 15 because I've found direct flights to europe that have a duration of 15 hours.How long can A plane stay up in the air?9 days, 3 minutes, and 44 seconds is the longest any plane has stayed in the air %26lt;%26lt;without refueling%26gt;%26gt;.
