Ryanair has disclosed that 315,000 of its passengers have been impacted by its decision to cancel 2,100 of its flights over the next six weeks.
The customers have now been contacted with offers of alternative flights or refunds, says the budget carrier.
Ryanair had previously estimated the number of passengers affected by the cancellations would reach 390,000, but has now reduced that figure because "forward bookings in September were 90% but October were 70%".
The airline expects that by close of business today, it will have reaccommodated more than 175,000 passengers on alternative flights and given refunds to another 63,000.
It expects 300,000 impacted passengers, or 95% of the total, to have been booked on alternative routings or given refunds by 24 September.
"We have taken on extra customer service teams to speed up the rate at which we accommodate and action alternative flight requests or refund applications," states Ryanair's chief marketing officer Kenny Jacobs. "We expect to have the vast majority of these completed by the end of this week."
The Dublin-based carrier has been forced to cancel 40-50 flights per day until the end of the summer season in late October because of a squeeze on crew availability over the next six weeks.
