Stop it! Is that really Prince William?

Stop the world. One of the biggest stars on the planet was spotted on a plane in the US sitting in economy.

No Royal treatment necessary for this plane-travelling Prince.

Prince William, 31, has shocked fellow travellers by flying economy from Memphis after a wedding.

Eli Ross, an American television reporter, was on the same flight as the Duke of Cambridge and managed to take a photo of him.

Eli posted the sneaky snap to twitter captioned:  “I am still amazed #Prince William flies COACH. That’s pretty humble/awesome. Who knew?”

William was apparently taking the domestic flight to Dallas on his way home London after attending the wedding of Prince Harry's good friend Guy Pelly.

The flight was reportedly funded by Will himself, who was spotted holding his own hand luggage while surrounded by his Scotland Yard Royal Protection Squad.

Looks like we all travel like Royals after all.
