We've heard the horror stories of having a little too much booze on a flight and becoming an absolute mess by the time the plane lands.
And even though alcohol affects you more when you're up thousands of feet in the air, it actually doesn't bother flight attendants as much as other drinks.
But the one beverage that flight attendants really can't handle? Diet Coke.
Jet, from the blog, These Gold Wings, says that it really annoys the cabin crew when people order it.
"As you may know, the aircraft cabin is not pressurised to sea level, but rather to the equivalent of about seven or eight thousand feet.
"This means some passengers might feel a little light headed or that alcohol affects them almost twice as much as it would on the ground.
"It also means soft drinks foam up a lot more when poured out of a can, and the worst culprit for this is Diet Coke," he said.
"I literally have to sit and wait for the bubbles to fall before I can continue pouring.
Jet continued, "If all three passengers ask for Diet Coke I'll often get them started, take another three drink orders, serve those, and then finish the Diet Cokes."
So, maybe it would be best not to order Diet Coke in future… or you know, just pour it out yourself.
