Ed Iacobucci, founder and former chairman of software maker Citrix Systems, on April 25 announced his latest project–regional, per-seat, on-demand air-limo service using Eclipse 500s. His company, DayJet, has placed a firm order for 239 Eclipse 500s and taken options for 70 more and plans to start service with the very light jets by the middle of next year. Iacobucci hopes to transform regional business travel in the U.S. by offering his no-frills air-limo service for a 40-percent premium over full-coach airline fares.
