The FAA has given Boca Raton, Fla.-based DayJet the green light to use Eclipse 500 very light jets (VLJs) for its “per-seat, on-demand” service, the company announced yesterday. The addition of the five-seat twinjets to DayJet’s Part 135 operating certificate “is the culmination of more than five years of dedicated work to develop the world’s first fully automated fleet operations system,” said DayJet president and CEO Ed Iacobucci. So far the start-up air taxi has 12 Eclipse 500s in its fleet, which it will use to serve five Florida cities, and expects to take delivery of eight more of the VLJs in the next 30 days and have between 30 and 40 airplanes by year-end. DayJet told AIN that it will start “pre-launch” service for select customers sometime next week, though the “official” launch for all of the 250 companies (about 1,200 individual customers) that have signed up as DayJet members will take place early next month. A service expansion announcement of two to four additional cities could come by the end of next month, DayJet said.
