Executive charter operator VistaJet has ordered six more Bombardier aircraft for its planned expansion into markets in West Africa, the Middle East and Russia. The deal announced in Farnborough includes four Global Express XRS and two Challenger 605 jets that are due for delivery in 2011 and 2012. The additional aircraft will expand VistaJet’s fleet to more than 30 airplanes.

VistaJet outfits all its jets with identical cabins and the same distinctive silver-and-red paint scheme, following a trend started by fractional ownership providers. But unlike fractional operators, VistaJet sells blocks of time rather than aircraft shares. The company has a policy of keeping its airplanes for no longer than three years.

VistaJet founder Thomas Flohr said the firm is seeing signs of a resurgence in demand for long-range airplanes, particularly in Russia as the economy recovers. Business in Europe has fallen off in recent months, but he noted that VistaJet was one of the few private jet operators to report a profit last year.

Bombardier also announced a firm order for four Global Express XRS jets from undisclosed customers in Russia. It said the total value of those orders is approximately $213 million based on 2010 list prices.
