It's often dreaded by both parents of small children and those seated near them - a noisy child on a long flight.
There are plenty of tips online about how to entertain children while flying, but a cabin crew member from Virgin Atlantic says she's found the secret, and it's all about the seat selection.
"If they're little enough, try and get a bulkhead seat and request a bassinet. This means you can hopefully kick back, sleep, eat and watch a few films without the worry of disturbing your little one," said Rebecca Love, who has been working at Virgin Atlantic for eight years.
"Window seats if possible are always a good idea, as they provide a nice distraction and can also offer soothing views for when trying to get toddlers to sleep."
Being stuck at the window seat can be an issue, though. Toddlers tend to want to visit the bathroom quite often.
"It is always worth sitting near toilets too, as children tend to have a habit of going more frequently when flying, so that saves having to make any mad dashes!" Love told The Mirror newspaper.
Love says if your child is active or easily distracted, aim for a daytime flight so you don't have to worry about interrupting yours or anyone else's sleep.
"Parents should not be scared of letting your little one walk up and down the aisles and even down to the back galleys. Children love the change of scenery," Love said.
That might just provide a bit of entertainment and distraction for the cabin crew as well.
