British budget airline Flybe Group said it had booked lower passenger revenue per seat for the fourth quarter and that it would break even on pretax profit for the full year 2015.
The company, which said it has no exposure to the Swiss franc, said passenger revenue per seat fell 3% in the quarter.
About 36% of seats were sold as on 20 January, compared with about 34% a year earlier.
"The benefit of lower fuel prices, given our hedging strategy, will not flow in significant amounts until 2016/17, though we will be covered in case fuel price increases next year." the company said.
Flybe serves a number of Irish airports, including Knock, Donegal, and Waterford.
