If you’ve ever been on a long haul flight then you know the pain of walking past all the people in business class with their leg room and champagne on your way to cattle class. It’s the most jealousy-inducing moment in your life and it’s easy to spend the rest of your flight fantasising about how good it would be to get seated up front in business - or even better, upgraded to first class.

This fantasy isn’t entirely out of reach according to Dawn Morwood, Co-Director of Cheap Deals Away UK. She said: “It’s common for people to believe free upgrades are just a myth or only happens in films, but they're very real. Airlines regularly move passengers to higher cabins, and knowing how to position yourself as a prime candidate can make all the difference.”

That’s why Dawn has shared her top tips for securing an upgrade. The first way to improve your chances is simple - just ask.

Dawn said: “When you check in, smile warmly and simply ask, ‘Are there any upgrade opportunities available today?’ This phrasing is important - it's polite, direct, and shows you understand upgrades aren't guaranteed.”

She also said timing is equally important: “Check in early, when more premium seats are likely available, but not during peak busy periods when staff are rushed,” says Morwood. “And always ask discreetly - never demand an upgrade in front of other passengers.”

Another tip is to dress for success - but this doesn't mean you need to be in a ball gown or three piece suit.

Dawn said: “Smart-casual clothing sends a signal that you'll ‘fit in’ with the premium cabin environment. Think neat jeans or trousers, a collared shirt or nice top, and clean, decent shoes.”

This doesn't mean airlines only upgrade well-dressed passengers, but when staff have to make quick decisions, looking presentable works in your favour.

It’s also a good idea to share with the staff if you’re celebrating something - honeymoons, anniversaries or significant birthdays could lead to special treatment. Just make sure it’s true when you mention it.

Dawn added: "I've seen couples get upgraded because they mentioned their anniversary. One pair even received complimentary champagne in business class."

Keeping an eye out for oversold flights can also help your cause. Flights during school holidays or weekends are best for this.

When economy cabins are oversold, airlines may need to move passengers to premium cabins.

Dawn said: “If you're flexible with your travel plans, these flights offer better upgrade opportunities.”

When it comes to securing upgrades there are a couple of things you should never do.

Dawn said: "Most people make simple mistakes that instantly ruin their chances of an upgrade. Asking loudly in front of other passengers, arriving at the gate just before boarding, or being rude to staff are all guaranteed ways to stay in economy.

"Remember that upgrades are at the discretion of airline staff – they're more likely to reward polite, appreciative customers who've shown loyalty to their airline.

"Even if you're nervous or excited, stay calm and friendly. A little genuine courtesy goes a long way when upgrade decisions are being made."
