US-based low-cost airline JetBlue has revealed a new codeshare agreement with Serbian flag carrier Air Serbia.

The agreement extends and formalises the airlines' previous relationship.

Under the partnership, both companies will distribute their marketing codes ensuring flights are available to passengers of both airlines and appear on respective websites.

Air Serbia’s "JU" airline code is set to provide routes to more than 25 North American destinations through the JetBlue network.

JetBlue placed its “B6” airline code on Air Serbia-operated non-stop flights from New York’s John F Kennedy International Airport (JFK) and Chicago's O'Hare International Airport (ORD) to Belgrade’s Nikola Tesla Airport (BEG).

Air Serbia CEO Jiri Marek highlighted how this partnership will expand travel opportunities in the Balkan regions.

Marek said: "We are very pleased with the future collaboration with JetBlue and believe that this significantly enhances the travel possibilities between the United States and destinations within the Air Serbia network, especially those in the broader Balkan region,”

JetBlue passengers will benefit from the simplicity of utilizing a single booking to continue their travel to European nations covered by Air Serbia.

JetBlue CEO Robin Hayes highlighted how the new agreement extended the previous relationship between the companies.

Hayes said: "We continuously look to expand our partnerships to offer more options to our customers. Air Serbia has been a successful interline partner since 2016 and we see great potential with this new codeshare.

“We welcome customers from Air Serbia aboard our flights, so they can experience our low fares and great service.”

JetBlue reportedly intends to add its "B6" code to more flights connecting Belgrade with other locations in Europe.
