European low-cost airline Ryanair said on Thursday it was not changing its profit forecast despite rising fuel costs, saying it still expected to post a 10 percent rise in full-year earnings. "We see no reason to change our guidance, nor would we raise our guidance," Chief Executive Michael O'Leary told Reuters on the sidelines of the World Low-Cost Airlines summit in Amsterdam. "We had a fair idea of what fuel would be at the end of Q1 and we are almost fully hedged to the end of March." Ryanair, Europe's largest no-frills carrier, said in August it expected a full-year net profit of 295 million euros ($362.4 million), having reported a 21 percent rise in net profit for the first quarter to end-June of 64.4 million pounds. O'Leary also said he still expected yields, or average fares per passenger, to rise 1-2 percent in the second quarter on the same period last year. However, he said said market conditions remained challenging and it was difficult to predict what would happen this winter. "The winter is always a hard time to predict. We have a good degree of visibility into October and November but almost none for January, February and March." --More 1053 Local Time 0753 GMT
