easyJet is actually not just one low-cost flight operator company, but three. easyGroup owns three airlines and a long list of other businesses from pizza to cinemas, buses and hotels. easyJet airline Co.Ltd. is based at London Luton, easyJet Switzerland at Geneva and easyJet Europe in Wien, Austria. easyJet Europe was established after Great Britain announced that it would leave the European Union. It's vital for easyJet to be based inside the EU to benefit from EU's open skies policies.

This Airbus A320 in the picture belongs to easyJet Europe. That can be seen from the picture only by noticing the small EU and Austrian flags by the rear door of the plane. easyJet Europe has 91 A320 and 45 A319 planes in use in 2019.
