Ryanair, Jet2, BA, TUI and easyJet rules for bringing your own alcohol on-board

Travellers are widely banned from consuming their own alcohol on-board a flight, but they are allowed to bring sealed bottles into the cabin.

There's a whole host of restrictions travellers need to be aware of, and flicking open a can of beer or popping open a bottle of wine, unless you've bought it from a flight attendant, is strictly prohibited on all airlines.

It's more than likely you've bought a discounted bottle of your favourite tipple at the duty-free shop in the departures lounge, but you will need to wait until you land to enjoy it responsibly.

We've rounded up the rules you need to be aware of on some of the UK’s most popular carriers.

Ryanair allows passengers to bring food and non-alcoholic beverages on board, so long as they fit within the airline’s cabin bag size and weight restrictions. However, hot drinks and alcoholic beverages are not permitted onboard.

Additionally, alcohol with an ABV of more than 70% (140% proof) is not permitted onto the aircraft either through carry-on luggage or in your checked-in baggage.

If you wish to drink onboard, duty-free purchases of tobacco and alcohol may also be available on all flights to the EU from non-EU member states.

Jet2 explicitly states that passengers may not bring alcohol on board their carriers for the purposes of consumption whilst on the aircraft, with the brand reminding passengers that it is an offence to be drunk on any aircraft.

Only alcoholic drinks purchases on board can be consumed during the flight, but the airline reserves the right to serve alcoholic drinks to passengers at their absolute discretion.

Jet2 also states that passengers are not permitted to carry: "Items which in our reasonable opinion are unsuitable for carriage by reason of their weight, size or character or which are fragile or perishable or which may affect the safety, health or comfort of other passengers or crew, this may include hot or strong smelling foods and drinks”.

When it comes to the carry of alcohol into the cabin, British Airways says there is no limit on the number of alcoholic beverages you can travel with as long as their alcohol volume is below 24%. Though consumption of your own alcoholic beverages onboard is prohibited.

Still, you can carry up to five litres of alcohol with an ABV between 24% and 70%. This can travel in your cabin bag if you purchased it in the airport duty-free shop. Drinks above 70% alcohol volume are not permitted on board any British Airways aircraft in either checked baggage or hand baggage.

TUI passengers are permitted to bring alcoholic beverages into the cabin with some stipulations. Alcoholic beverages containing more than 24% but no more than 70% ABV are permitted in checked baggage and carry-on baggage.

The beverages need to be in retail packaging and be no more than five litres per individual receptacle, with no more than five litres total net quantity per person for such beverages.

easyJet passengers are permitted to bring alcohol bought in the airside departure lounge into the cabin, as long as it’s unopened. Alcohol must be lower than 70% abv, and packed either in an airport shopping bag or in your cabin bag.

It’s strictly forbidden to drink any alcohol that has not been purchased on board the aircraft and those found consuming their own alcohol may face prosecution.

Ryanair's CEO Michael O'Leary has more recently spoken out about drunk passengers causing mayhem on-board, after binge-drinking in the airport before getting onto the plane. In some heated incidents, brawls have erupted and cabin crew members have been assaulted.

He has called for a two-drink maximum restriction at airport bars to clamp down on this issue, which is not just confined to the budget airline. In the UK, it's a criminal offence to board an aircraft while drunk, or to be drunk while on-board.

Fines of up to £5,000 can be slapped on offending passengers with up to two years in prison. Drunk customers who cause chaos mid-flight could face a huge £80,000 bill to cover the airline's costs if it is forced to divert.

Travel Supermarket says: "The law also gives cabin crew significant authority. They have the right to refuse to serve alcohol to any passenger and if they believe someone is drunk, they can take measures to restrain them if necessary."
