British low-cost airline easyJet said its first-quarter revenue rose 15% on a year ago, with passengers up 10%.
The airline said in a statement that for the full year it expects a jump in profit before tax of between 40% and 50%.
For the year ended last September the company reported a 56% rise in pre-tax profit to £129m.
Although oil prices have fallen back, the airline will have a bigger fuel bill in the first six months of this year.
'In spite of the fall in fuel prices from the summer highs, our average fuel cost, after hedging, for this first half will be approximately $650 per metric tonne, 7% higher year-on-year,' it said.
EasyJet's total revenue per seat grew 4% in the three months, with total first-quarter revenue of £366m, up 15% on January 2005.
EasyJet said its load factor - a measure of how many seats it filled- was up 0.7 percentage points at 74.9% in January.
The airline said passenger numbers in January rose 11.1%.
