(CNN) – A method commonly used by airline passengers to obtain cheaper fares is at the center of a judicial dispute between a German airline and one of its customers.

Lufthansa drove a passenger, who did not show up for the final leg of his trip, to court for the obvious purpose of suppressing the "hidden city" ticket office.

The practice implies that passengers leave their trip at a point of call, instead of establishing a last connection.

For example, a person traveling from New York to San Francisco could book a cheaper trip from New York to Lake Tahoe with a stopover in San Francisco and get off there, without taking the last leg of the flight.
According to a court document, an anonymous passenger, booked a return flight between Oslo and Seattle, with a stopover in Frankfurt. The passenger used all the steps of the outward flight but did not catch the Frankfurt-Oslo return flight. He instead flew to a separate Lufthansa reservation between Frankfurt and Berlin.



Lufthansa's lawsuit was aimed at a "loophole" of the "hidden city".

Lufthansa considered this to be a violation of their terms and conditions and seeks compensation in the amount of € 2,112 (approximately $ 2,385).

A Berlin district court dismissed the complaint in December, but Lufthansa spokesman confirmed to CNN that the company "has already appealed against this decision".

In 2014, United Airlines and Orbitz filed a lawsuit against 22-year-old Aktarer Zaman, who founded the Skiplagged.com website, which helps travelers find cheaper flights using the "hidden city" strategy. ".

the case was sent in 2015 after the District Judge of the Northern District of Illinois stated that the court did not have jurisdiction to try this case because Zaman did not live or work in that city.
