The FAA has authorized DayJet to use Eclipse 500TM very light jets in its operations, the company announced on Wednesday. DayJet is preparing to use its fleet of VLJs to launch "Per-Seat, On-Demand" jet service. "This milestone is the culmination of more than five years of dedicated work to develop the world´s first fully automated fleet operations system," said Ed Iacobucci, DayJet president and CEO. In the coming weeks, DayJet says it will begin taking online reservations. The company, based in Boca Raton, Fla., operates under Part 135 air charter rules. Customers can schedule flights online according to their own schedules. The more flexible the passenger can be for departure and arrival times, the lower the price of the seat.
