GainJet Aviation (GNJ, Athens) has added a first G700, also the first unit of the type registered in Greece. Its president and chief executive, Ramsey Shaban, confirmed to ch-aviation the aircraft is configured for up to 16 passengers, will be predominantly based at Athens, and is available for charter.

The 2024-build ultra-long-range jet, SX-GJB (msn 87050), was initially under completion with Jet Aviation (Switzerland) in Basel/Mulhouse/Freiburg, CH, where it arrived directly from Savannah International as N750GA on July 11, 2024. It resumed operations on March 25, 2025, with a test flight, followed by additional test flights into early April. The aircraft was deregistered in the United States on April 16 and delivered to Athens the following day as SX-GJB.

The new G700 joins another Gulfstream Aerospace aircraft in GainJet Aviation's fleet, a G650ER. The company also operates two Challenger 604s, two Challenger 605s, and a Global Express XRS, which was recently inducted.

GainJet Ireland also operates a fleet of Gulfstream jets, including two G550s, a G650, and a G650ER, alongside a Hawker 800XP dedicated to air medical services in partnership with Reva (United States of America). The group also manages additional aircraft placed in other registries.
