When headed out on or returning from holiday, the flight should simply be the first step towards a relaxing time away from home, or a chance to unwind before settling back into normality.

But somewhere in between boarding a flight and landing, it seems some travellers have forgotten that they're sharing a cabin with a hundred or so other people.

Gone are the days when the biggest in-flight grievances were crying babies, overly reclined seats and armrest hoggers. Instead, there's a new wave of irritating habits creeping into the cabin.

From filming TikToks to attempting yoga stretches or deciding it's time for a manicure, there's no shortage of ways that passengers have found to test the patience of their cabinmates.

According to new research from Booking.com, nearly half of Brits believe passengers are becoming far too comfortable at 30,000ft, with many treating the cabin as an extension of their own living room.
