UK budget carrier EasyJet estimates that disruption over the course of the year has had a £150 million ($187 million) impact on pre-tax profit.
The airline’s pre-tax figure for the 12 months to 30 September fell by 28% to £495 million.
Revenues for the period were flat at just under £4.67 billion, with revenues per seat falling by 6.9% at constant currency.
The airline says revenue per seat fell as a result of higher capacity and “aggressive” pricing, a “cooling” of demand relating to customer confidence, and the weakening of the UK currency.
EasyJet adds that it experienced “severe” disruption over the period, with more than 8,300 flight cancelled, diverted or delayed.
Cost per seat, at constant currency, was down by 4.6%, and by 1.1% excluding fuel.
EasyJet recorded a 6.6% rise in passenger numbers to 73.1 million with a slightly-higher load factor of 91.6% over the year.
