Re: "maintain operations independently of Ctrip"
If you have two different companies that service two completely different markets and both are profitable, why would you bring them together?
The only reason would be if you think you can leverage economies of scale. but considering regulations in europe on data protection, I'm sure Ctrip decided not to open that can of worms by bringing the skyscanner servers to China. So now Ctrip collect the profits from Skyscanner, so they make Money back on the purchase and they have a profitable subsidiary making money in a market they arent in or trying to get into.
Seems a very reasonable basis to do the deal for me.
