Hotels probably, but I seriously doubt this for airlines. After all, a 13% commission would likely put the airline in the red for that booking.
Flying is one of the lowest-margin businesses in existence, and makes discount retail feel like a walk in the park.

I really agree, and it's really too bad, because I love their flight-booking product and I'm really rooting for the team, but both their hotel booking site and mobile apps are IMO worse than the incumbents, which falls well short of their "kicking everyone's ass" bar that they set for flights.
Confusing button placement, unclear comparison tools, incomprehensible color-coding, and a location-centric search... I just can't get behind it.
