The luxury of flying private at prices competitive to first and business class has become a reality with LunaJets. LunaJets enables travellers to purchase empty leg flights (private jets returning home empty) within Europe, Middle East, Russia and USA at prices as low as 50 - 80% off a full private jet fare. Travellers looking to avoid the hassle of overcrowded airports, lengthy check-in times and long delays on commercial airlines can enjoy all the luxury services associated with private aviation: VIP handling and transfer services, a dedicated customer services team and luxury on-board service at substantially reduced prices. Prices are calculated on the duration of the flight and are independent of cabin size. LunaJets also offers travellers the possibility to purchase single seats for flights less than 2 hours 30 minutes. Prices start at $1,200 and registration is completely free.
