A passenger only found out his lost luggage was in Amsterdam when a stranger messaged him on Facebook

A passenger says he only found out his lost luggage was in Amsterdam when a stranger contacted him on social media and is still waiting for his bag even though he told the airline.

Saith told Insider that he flew with Turkish Airlines from Istanbul to Amsterdam on August 27. He flew from Amsterdam to Newark Liberty Airport in New Jersey on an economy class United Airlines flight.

Saith filed a report with United Airlines after his bag didn't make it to Newark. Turkish Airlines tagged his bag with Newark as his final destination when he checked in at the airport.

Saith was unsure of what had happened to his bag. On August 31, he got a message from a stranger saying that they had found his suitcase. The bag had an address on it.

The stranger said that they found the bag after arriving at the airport. They said in one of the Facebook messages that it wasn't catalogued yet and was waiting for someone to pick it up.

Saith contacted United Airlines by phone and online. He said he contacted Turkish Airlines by email and on the social networking site.

Saith was going to attend a wedding. He said that his suitcase contained clothes, but no electronics except for a phone and toothbrush.

The situation was very frustrating, he said. He said he had been using the lost and found website every day, but hadn't found his bag.

"We are dedicated to delivering bags to customers' final destinations on time, and when we miss the mark we work hard to connect customers with their bags as quickly as possible," a United Airlines spokesman told Insider. Turkish Airlines did not reply.

The problem of lost bags has become worse this summer due to a combination of understaffing and technical issues. When flights have been changed last-minute or when luggage isn't transferred onto the second plane, it's happened.

There is a lot of lost luggage at airports. Some travelers use Apple AirTags to track their bags, while others only pack hand luggage.

According to DoT data, airlines lost an average of six hold bags for every 1,000 they took on nonstop domestic flights.
