Ryanair Holdings PLC revealed Tuesday it has attracted little interest from Aer Lingus shareholders for its proposed takeover of the rival Irish carrier and extended its offer period for acceptance.

Shares of European airlines tumbled Monday after budget airline Ryanair said its profit fell 85 percent in the recent quarter and warned it might not make money this year.

European stocks ended lower on Monday, dragged down by banks that fell on concerns over credit ratings at major U.S. mortgage lenders and by a rise in crude after recent sharp falls, which revived inflation worries.

Ryanair posted a 85 percent fall in first-quarter net profit on Monday as its fuel bill almost doubled and warned it could make a full-year loss of up to 60 million euros if oil prices  stayed high and fares fell.

From job cuts to fewer winter flights, airlines are looking for every way to battle high oil prices.

No-frills airline Ryanair said Thursday it will withdraw nearly a third of its aircraft from its major London base and suspend operations at seven other European airports because of high fuel costs and its failure to negotiate lower airport fees.
