You might recall an incident earlier this week when United Airlines prevented two teenage girls from boarding a flight from Denver to Minneapolis and instructed them to change out of their leggings because they were deemed inappropriate flight attire.

Unsurprisingly, the incident resulted in the airline receiving a lot of flack from men and women across the world, including some various high-profile United travelers – such as the likes of Chrissy Teigen, Patricia Arquette and Sarah Silverman – who were outraged at the company's dress code policy.

Some might say, the airline missed out on fashion's unstoppable athleisure trend. Denim isn't always a comfy flying option, as we all know.

As Joey Tribbiani would say: 'What was I thinking, these jeans have no give!'

Fortunately, sports brand Puma has come to rescue and is protesting United Airlines' leggings ban by offering flyers with the airline 20 per cent off leggings in their shops, according to Hellogiggles.

The brand tweeted a post about the discount with the phrase, 'we fly in our leggings', along with an image of two models jumping in the air wearing the elasticated attire.

Available until 9 April, the offer requires customers to bring a United Airlines plane ticket to a US Puma store location.

Of course, while the brand's efforts to promote inclusivity and protest against the airline's limiting dress rule is to be applauded, we can't ignore the fact it's also a clever ploy to sell more leggings.

However, you can't blame them for killing two birds with one stone on this one.

Unsurprisingly, other airlines have jumped on the bandwagon to encourage their customers to wear leggings on their flights.

Prepare to see a whole lot more elasticated waistbands and VPLs in the air this summer.
