Passenger numbers for the three months ending September 30 were a record 24.1 million, driving a load factor of 95.6%.
Passengers have benefitted from low summer fares across the network, easyJet said, particularly on beach markets from the UK.
The airline has also grown capacity by 8% in the final quarter compared to last year.
Headline cost per seat excluding fuel at constant currency is expected to increase by around 1% for the full year, in line with guidance.
EasyJet said it remained focused on cost however, and has continued to drive “structural improvements”, such as longer-term capacity-related deals with airports.
