The Globe and Mail reports in its Thursday edition that Bombardier said on Wednesday that Dubai-based private jet provider Vista Global has placed an order worth $1.18-billion (U.S.) for 40 Challenger 3500 business jets. A Reuters dispatch to The Globe says the order includes options for an additional 120 planes, which would bring the total value of all 160 aircraft to about $4.72-billion (U.S.). The deal comes amid sustained demand for private flying which is swelling business jet makers' order books. Challenger 3500 is an upscaled variant of Bombardier's Challenger 350 business jet and seats up to 10 passengers. Bombardier, which reported an 11-per-cent rise in third-quarter revenue in November last year, is considering raising production of private jets. Customer demand for aftermarket care of jets is also growing, leading to service expansion in the United States. Bombardier recently came under fire from U.S. President Donald Trump's threats to decertify its business jets over Ottawa's lengthy certification of jets produced by U.S. rival Gulfstream. However, that dispute seems to be at its end, with the head of the U.S. Federal Aviation Administration saying that certification was moving along satisfactorily.
