The airline was previously contracted to provide flights this winter season to Grenoble but it will now also operate to the Neilson Beachclub and Sailing holiday locations of Lemnos and Preveza, in Greece next year.
Germania first entered the UK market in 2013 and established its base at Gatwick.
Jerome Newton, director of sales for the UK, Ireland and France at Germania, said: “Having initially been contracted to operate flights on behalf of Neilson to Grenoble during the 2015/16 winter season, we are delighted to now be adding flights to Greece during the summer 2016 season."
Graham Rider, Neilson’s aviation manager, said: “We look forward to continuing to work closely with the airline to ensure that our Beachclub and Sailing guests, like our winter sports enthusiasts, arrive at their destination in comfort, style and - more importantly - on time.
Germania operates a fleet of 22 aircraft. It currently flies to more than 140 destinations across Europe, North Africa and the Middle East.
Germania‘s flights on behalf of Neilson will be operated using the airline’s Gatwick-based Airbus 321 to Grenoble during the winter months, and its Airbus A319s during the summer.
