EasyJet plans to replace the Go brand with its own logo. However, the registration by Go Voyages of the words Go Easy, used on its website in relation to travel insurance, may threaten easyJet's ambition to catch up with European no-frills leader Ryanair by purchasing Go Fly and Deutsche BA, a German domestic carrier also created by British Airways. The registration could affect easyJet's ability to market itself under the easy brand in France, says the prospectus.
