He didn't realize there was more than one Sydney until he was already on the plane.

Careless teenager Milan Schipper was in for quite the surprise when boarding a recent flight he thought was headed for Sydney, Australia.

The 18-year-old traveler was looking to take a flight from Amsterdam to the Australian city, when he stumbled across a flight that was roughly $300 cheaper than all of the others and though he came up on a deal.

According to CBC News, Schipper was planning to spend some time backpacking and potentially working in Sydney before starting college, but it wasn’t until he was already on the flight that he noticed he was headed in the wrong direction.

Schipper said he first noticed an issue when he landed in Toronto for a stopover and spotted an Air Canada plane.

He was surprised but boarded the plane, at which point he finally noticed what was going on.

“I saw the flight plan was going to go right, not left,” Schipper said. “It was about the time that I realized there was another Sydney,” he told CBC News.

It turns out, Schipper had booked a flight to Sydney, Nova Scotia, and he landed there only to find a blizzard approaching.

After explaining the situation to airport employees, Schipper was able to get an immediate flight back home.

He’s not the only one who has made the mix-up, as Schipper told CBC News there was a woman from the U.S. on his flight who had made the same mistake.

Several other tourists, including a British couple and travelers from Italy, have also made the blunder.
