Feb 6 (Reuters) - Online travel platform Expedia reported fourth-quarter results on Thursday that beat Wall Street estimates on the back of strong international travel demand, sending the company's shares up about 10% in overnight trading.

Travel demand has been strong globally, especially in Asia, where cross-border travel in Southeast Asian countries has helped drive up prices for hotels and other travel services.

Expedia also approved the reinstatement of a quarterly cash dividend and declared a first-quarter dividend of 40 cents per share.

Leisure travel demand has also remained steady in Europe, with growth driven by both domestic and long-haul trips from wealthy American travelers.

The company has also been reaping benefits from integrating all its brands, including Vrbo and Hotels.com, onto a single unified platform called "One Key".

On an adjusted basis, Seattle-based Expedia earned $2.39 per share in the fourth quarter, compared with the average analyst estimate of $2.04, according to data compiled by LSEG.

Total revenue rose 10% to $3.18 billion, beating estimates of $3.07 billion.
