Chart of EasyJet passengers flown performance (2016-2000)

Originally, much like Southwest, easyJet did not allocate seats – passengers took any available seats, with the option to pay for "Speedy Boarding" and be first onto the aircraft. Since 2012, all passengers are allocated numbered seats before boarding commences, as it was found that this does not slow down boarding times and could earn more revenue than Speedy Boarding. Passengers can pay an additional fee for certain seats such as the front few rows and overwing seats (which have extra legroom).
