Booking Holdings

Booking Holdings' Glenn Fogel, whose background is in mergers and acquisitions, was undoubtably not surprised when Airbnb bought HotelTonight. We'd be shocked if he and others hadn't kicked the tires.

Will Airbnb stick to its boutique and independent-only stance on hotels? It could put it at a serious disadvantage when it comes to competitors like Booking or Expedia in the long run. But if Airbnb winds up offering a wider swath of hotels, it could boost its brand even further. Either way, it's guaranteed to be interesting. We'll get the popcorn ready.

Arguments can be made for a number of sides, but the truth is there's no true winner or loser here, if we're being totally honest.

Traveloka is going after a slice of the Australian online travel market. That's brave. Even though the market is robust, the space is highly competitive. While Indonesia is popular among Australians, travelers still mainly prefer Bali, which is like their backyard. So what has Traveloka to offer?

Airbnb to Booking: "Yeah, right."

Kayak is looking to get leaner and more efficient. The restructuring, though, doesn't exactly mesh with the upbeat picture about the metasearch company that parent Booking Holdings described during its fourth-quarter earnings call this week.

Airbnb has dominated the discussion of alternative accommodations, but it appears as though Booking Holdings' apartment-rental business may be in a dead heat with its competitor. Airbnb's perceived lead may not be as great as many observers believe.

The fact that Booking Holdings and Expedia Group are leaning away from TripAdvisor is a wake-up call for many metasearch sites. However, travelers still love to use the damn things for comparison shopping, so there's that.

In a rush to scale, consolidated travel companies find themselves with outsized market share that often leads to muscling consumers to their advantage. With no good alternatives, how will travelers react to the pressure?

Expedia is an opportunistic company, and mergers and acquisitions are part of its DNA. The company has been quiet on this front for the past three years. It is sort of due to make another big splash.
