Dressing for the airport can be tricky as you need to find a comfortable outfit that will keep you warm on the freezing plane, but will be cool when you arrive in your sunny destination.
Most of us just throw on trousers and trainers, with a big old jumper stuffed in our bag, but a flight attendant has revealed that it's worth putting a bit more effort if you're hoping for an upgrade.
Speaking to WhoWhatWear, the steward explained that jeans and trainers are a big no no if you're eyeing up a fancier seat, giving a few options instead, reports the Liverpool Echo.
They said: "For an upgrade, it's all about looking the part. Smart but understated. You should look like you travel often. But don't be dripping in designer clothing. It helps; someone who is potentially due to get an upgrade can be knocked back if they aren't dressed suitably.
"When we fly, we have a strict dress code to follow. No jeans or trainers - so I always go for tight black trousers and a blazer or a dress. For men, chinos or trousers and a shirt are worn."
But don't worry, you won't be stuck in that uncomfortable blazer for the entire trip - as it's fine to change into something more snuggly once you've bagged your update and boarded.
They add: "I always carry trackies on long-haul, and it is acceptable for us to change on board."
This isn't the first flying tip we've had this week Cabin crew member Tommy Cimato revealed it's always best to avoid the window sleep if you're planning to have a nap on board.
While it's many people's favourite seat option, he warned that you should never learn on the window to fall asleep because you can't be sure if it has been cleaned or not, and you certainly don't know how many people have done the same before you.
He said: “Do not fall asleep or lean your head on the window."
“You are not the only one that has done that and you don't know how many people or children have wiped their hands or other things all over the window," he pointed out.
But windows aren't the only dirty spots passengers should keep in mind.
The seats themselves can also be a cause for concern. Of course, you can't avoid the seats in the same way as the windows, but you can stick to trousers or other clothes that cover your legs for a more hygienic flight.
The choice is yours, but Tommy strongly recommends steering clear of shorts.
He said: “Don’t or try not to wear shorts when you're on a plane.
“It's the same thing as the window – you never know how clean it's going to be, so if you have pants, you're going to have less germs.”
