EasyJet plc, styled as easyJet, is a British multinational low-cost airline group headquartered at London Luton Airport. It operates domestic and international scheduled services on over 1,000 routes in more than 30 countries via its affiliate airlines EasyJet UK, EasyJet Switzerland, and EasyJet Europe.

In 1995, EasyJet was established by Stelios, being the first company in what would later become the easyGroup conglomerate. 

EasyJet has seen expansion since its establishment in 1995, having grown through a combination of acquisitions, and base openings fuelled by consumer demand for low-cost air travel. 

The group, along with associate companies EasyJet UK, EasyJet Europe and EasyJet Switzerland, operate more than 300 aircraft. It has 29 bases across Europe, the largest being Gatwick. In 2014, the airline carried more than 65 million passengers, making it the second-largest budget airline in Europe by number of passengers carried, behind Ryanair.

All flights operating within the European Union were to be operated, by July 2019, by EasyJet Europe, which operates 45 Airbus A319 and 91 Airbus A320 aircraft. Sister company EasyJet Switzerland operates 6 Airbus A319 and 21 Airbus A320 aircraft.
