The on-line travel business is coming out of its first major downturn. Who is positioned to benefit most from the current upswing? Expedia Inc (NASDAQ: EXPE) is being mentioned more frequently. So much so that the on-line travel giant announced a $3.5 billion share repurchase this morning.

Thomas Weisel believes Expedia is in the early stages of a potentially material turnaround, regardless of any LBO or buyback and has placed a $37/share price target, in a report published yesterday. Expedia's stock rallied late last week on news that it might be taken private. Barry Diller, the on-line travel giant's CEO, owns 58% of the voting stock.

Much of the on-line travel business has gone through considerable consolidation as financial buyers bought up Travelport (Cendant's on-line travel business) and Sabre Holdings, which owns Travelocity, was acquired by Silver Lake and Texas Pacific Group. The change in ownership helped add pricing discipline to the market.

Expedia has invested close to $1 billion in developing software to improve services and develop new products. So much for believing the Internet has low barriers to entry. Who is going to be able to replicate a decade of code writing to surpass the purest Internet travel play. The answer is no one.

Expedia changed management a year ago and is beginning to see the fruits of new strategies. In addition, Expedia appears to benefit from economic slowdowns as its on-line reservation platform is a great vehicle to reduce excess hotel room inventory. Stock upgrades, LBO speculation and improved operating performance all bode well for Expedia shareholders.
