Prince William and Kate Middleton fly easyJet

In this era of European austerity, even Prince William and Kate Middleton are watching their spending. 

The royal couple flew the budget airline easyJet home from their vacation in the Alps Sunday, Marie Claire said.

Will and Kate boarded their flight early with their security team as other passengers Tweeted about it, the magazine said. 

The trip was the couple's way of celebrating the Valentine's Day they missed because Prince William was stationed in the Falkland Islands, MSN reported.

While their memories of the trip may be priceless, the UK's Daily Mail points out Will and Kate's tickets for the Geneva to Manchester flight may have cost as little as £60 each. 

And the royals didn't get to skip security. Said the Daily Mail: 

They went through the usual security checks before boarding, and received no special treatment in the air.

The paper noted that the flight wasn't Will and Kate's first on a budget airline.

The Duke and Duchess of Cambridge flew the budget airline Flybe when returning to the Manchester area from a wedding in Edinburgh last year. 

Prince Harry also has been spotted aboard EasyJet, MSN said
