Many people are planning an Easter getaway this year and many families have already started planning their summer holidays. With that in mind, air travel experts have issued a warning to passengers that if they break certain rules while flying, they could face a hefty fine or even arrest.

While most people are aware of restrictions on hand luggage and liquids, experts at Northerner have shared four lesser-known rules that could land travellers in serious trouble if ignored. And it’s probably worth paying attention to them.

It’s common to enjoy a drink at the airport before take-off, but passengers have been warned not to go too far.

Being drunk and disruptive mid-flight can force a plane to divert, leading to fines of up to £80,000.

Airlines like EasyJet and Wizz Air have had passengers escorted off flights in recent weeks due to alcohol-related issues.

Smoking is banned on all commercial flights - and lighting up in the air comes with serious consequences.

Not only is it a major fire risk, but passengers caught smoking could face fines of £5,000 or more, and in some cases, even criminal charges upon landing.

Travellers struggling with nicotine cravings are advised to use nicotine pouches instead.

Failing to follow cabin crew directions - such as ignoring the seatbelt sign - can result in arrest or being restrained during the flight.

Cabin crew have the authority to detain disruptive passengers and pilots can return to the departure airport or divert the flight altogether if safety is compromised.

“Flight attendants may seem friendly and welcoming, but don’t underestimate the power they have to ensure in-flight safety,” the experts said.

Vaping is also banned by many major airlines, including British Airways, Jet2, EasyJet, Ryanair and Wizz Air.

Those caught can face fines of thousands of pounds, be banned from flying with the airline in the future, and may even be reported to the police.

The experts said: "If you are a passenger who breaks the rules and decides to vape on the plane, you could face a hefty fine, which in the UK can run to thousands of pounds.

"Other consequences may include being banned from flying with the airline in the future and even leave you facing criminal charges."
