Air Serbia (JU, Belgrade) has wet-leased a single B737-700 from Greece's Lumiwings (L9, Foggia Gino Lisa) to supplement its in-house capacity during the peak summer 2022 season.

SX-LWC (msn 30659) was ferried from storage at Volos to Belgrade on May 21, 2022, and began operating for Air Serbia the next day, Flightradar24 ADS-B data shows. The Serbian carrier confirmed the wet lease will continue throughout the summer 2022 season.

Lumiwings reverted to its original business model of ACMI/charters in January 2022, after its domestic scheduled operations in Italy proved unsuccessful. The Greek carrier operates one B737-300 (in storage at Craiova) and the single -700.

In turn, Air Serbia's in-house fleet comprises nine A319-100s, two A320-200s, three ATR72-200s, two ATR72-500s, and two ATR72-600s, the ch-aviation fleets module. While reliant on Boeing aircraft in the 1990s and 2000s, it gradually retired all of them through the 2010s. The last three B737-300s, operated by now-defunct leisure division Aviolet (Belgrade), were retired by mid-February 2020.
