easyJet fleet statistics
easyJet currently have a fleet of 248 A319/A320 aircraft.
We have now retrofitted 88 aircraft with Vortex Generators and expect to complete the
100 th aircraft in early June.
In addition to the 88 aircraft retrofitted, we have in the meantime taken delivery of 37
new aircraft with pre-fitted modifications.
This means that we now have 125 aircraft with vortex generators, just over 50% of our
overall fleet.
We expect that our entire fleet will be compliant by March 2018, this represents 197
retrofit procedures.
At Peak Summer 58 of our aircraft are currently based in Gatwick
As of today, 56% of aircraft at LGW are compliant, by peak Summer (July) this will rise
as we disproportionately deploy these aircraft to Gatwick Operations

Future fleet expansion/replacement
easyJet currently have a fleet of 248 A319/A320 aircraft.
The future replacement and growth program is modelled around the A320neo aircraft
In the next 6 years we will take delivery of a minimum of 130 new A320neo aircraft
Gatwick fleet size currently sits at 58 aircraft (seasonally dependent)
All new aircraft in to the easyJet fleet will have vortex generators pre fitted
Fleet delivery plan subject to change
