In March 1998, EasyJet purchased a 40% stake in Swiss charter airline TEA Basle for three million Swiss francs. The airline was renamed EasyJet Switzerland and commenced franchise services on 1 April 1999, having relocated its headquarters to Geneva International Airport. Geneva was EasyJet's first new base outside the United Kingdom. In 2002, rival airline Go Fly was purchased for £374 million; the airline inherited three new bases from Go, at Bristol Airport, East Midlands Airport and London Stansted Airport; the acquisition of Go almost doubled the number of Boeing 737-300 aircraft in the EasyJet fleet.
