I’ve never heard of Global Airlines but they have a website. The site doesn’t tell you very much. Apparently the founder runs homesharing site HolidaySwap.com, which I’d never heard of.
However they report acquiring an Airbus A380 from Doric Aviation, with plans to take delivery of 3 more of the used aircraft in the coming months in order to launch service from London to New York and Los Angeles in the spring of next year.
