British low-cost airline easyJet reiterated that it still expected to see full-year pretax profit growth of 40 to 50 percent while reporting an 8.4 percent rise in August passenger traffic on Thursday.

EasyJet, Europe's second-largest budget carrier after Ryanair, said its August load factor was 89.2 percent.

The group said it cancelled a total of 469 flights in August and expected the impact from the cancellations, passenger assistance and compensation over the period of the disruption to be about GBP4 million pounds (USD$7.5 million).

Flights from London were disrupted in August following a security alert imposed after police said they had foiled a plot to bomb planes.

Budget carriers such as Ryanair and easyJet rely on rapid turnaround times at airports to minimize costs, and the delays from extra security checks have slowed operations for all carriers.
