Kuwait Airways (KU, Kuwait) has reportedly suspended sales of its intra-European flights following an anti-discrimination lawsuit filed against the carrier in Switzerland.

As with a case filed in the United States in 2013, an Israeli citizen brought the suit against the airline last month after it refused to sell Israeli citizens a ticket between Geneva and Frankfurt Int'l on the grounds of their nationality.

According to the Lawfare Project, the suit, filed with the Swiss Federal Office of Civil Aviation (FOCA), says the carrier violated the Swiss Penal Code as well as the Swiss constitution, which protects individuals from discrimination based on race, religion and ethnicity.

The carrier, in turn, has suspended its other Fifth Freedom service - Paris CDG-Rome Fiumicino-Paris CDG - as a precautionary measure to avoid “further civil and criminal charges”.

Kuwait Airways ceased sales of its London Heathrow-New York JFK-London Heathrow flights in December last year after the US Department of Transportation (DOT) ruled its unwillingness to sell tickets to Israeli citizens violated US anti-discriminatory laws.
