Backing: Microsoft founder Bill Gates
Bill Gates-backed Signature Aviation swung back into profit last year.
The private jet services firm, which offers everything from VIP lounges, limousine booking and sustainable plane fuel at airports worldwide, made £55million in 2021, against a £30million loss in 2020.
Turnover soared to £2.1billion from £1.3billion in the same period.
Signature Aviation was snapped up by private equity giants GIP and Blackstone, and Bill Gates's investment vehicle Cascade in a £3.5billion takeover in December 2020.
At that time, the firm was listed on the FTSE250 and chaired by City veteran Sir Nigel Rudd.
He was among a succession of directors to resign last year following the deal.
Private jet firms were some of the best performing aviation firms in the pandemic as the ultra-wealthy turned to them to go on holidays and business trips.
