Spanish airline Vueling on Tuesday reported third quarter operating profits up 175 percent from a year earlier and said it expects demand to remain relatively stable in the fourth quarter of 2009.

Operating profits for the low-cost company, which merged with Iberia's subsidiary Clickair in July, reached EUR68.1 million euros, as revenues rose 69 percent from a year earlier to EUR259.2 million.

"In current circumstances, Vueling expects to report even better results in 2010 than in 2009," the company said, adding that more than 60 percent of the merger synergies will be felt next year.
