A letter in a package from a company seeking an airline to fly domestically to Europe is fake, authorities said Thursday.

The letter from a man in the Netherlands, purportedly from a travel company, is addressed to Delta Airlines, a regional carrier of the U.S.

Airlines have long tried to avoid paying bribes for planes to fly to Europe because it’s considered unethical.

The letter says Delta has no direct connections to any government or company.

Delta Airlines, based in Atlanta, Georgia, did not immediately respond to a request for comment.

A company called Delta Airlines said in a statement that the letter is not authentic and that the company is looking into the matter.

Delta said in its statement that it has contacted the U,S.

Postal Service and the U: the government in charge of shipping goods and the post office.

It said Delta’s investigation is ongoing.

The airline, which operates more than 2,300 planes each year, says its flights will be booked by the airlines.
