A smartly dressed, single guy in his 30s is the passenger most likely to get a free upgrade according to a survey of 700 cabin crew by Skyscanner.
The survey found that nearly two-thirds (61%) of cabin crew have given someone a free upgrade and it's single guys that are bagging the best seats.
At the other end of the scale, the flyers voted least likely to get an upgrade are women in their late teens, wearing revealing clothing and travelling as part of a group.
For those who don't fit the bill, crew have outlined how passengers can up their chances of getting that elusive free upgrade. While a few manners will go far, frequent flyers and solo travellers are odds-on favourite to get bumped up to Premium, when seats become available.
Almost three quarters (72%) of cabin crew said they were more inclined to offer a free upgrade to a passenger who was flying alone. Other factors that increase the likelihood of escaping Economy are being a frequent flyer and having an injury. Nearly two thirds revealed that a passenger with a broken limb was more likely to get the Premium experience for free.
In a separate poll of passengers, the company found that travellers are so keen to get a Premium seat that three quarters would willingly lie their way to a free upgrade. More than one in ten would pretend to be newlyweds (14%), 6% would feign illness or injury and 7% would ditch their partner and pretend to be travelling solo if it increased their chances of getting upgraded.
