We've all heard the rumours that you're more likely to be offered an upgrade if you look the part, travel regularly - or are on your honeymoon.
And according to a survey by last minute.com, Britons have no qualms about stretching the truth if it helps them to get a better hotel room or a business class seat on the plane.
The survey reveals that almost a quarter (23 per cent) of British travellers have lied about being engaged or on honeymoon just so that they can have a taste of luxury without the hefty price tag.
In fact, it's become so common that holidaymakers have invented an additional 11.5 million 'marriages' - which is 42 per cent more than the actual number of UK weddings (27.1 million).
Mark Maddock, Managing Director of last minute.com UK and Ireland, told the Daily Mail: "With so many bold Britons negotiating for an upgraded experience at the last minute, there's a clear demand for luxury without the price tag.
"The good news is, at last minute.com we offer everyone the honeymoon treatment and have a range of hotel rooms that offer a five star experience with a three-star price tag."
