Expedia plans to buy Orbitz in a $1.34 billion merger in Feb. 2015. The merger is in response to changes in the hotel and airline bookings business with new competitors changing the field. Google's travel site, and other newer sites in the hotel business such as Airbnb are posing a challenge to established sites Priceline.com and Expedia. In addition the airlines have improved their own sites and offer incentives to travellers booking directly. Delta Airlines and American Airlines now have sites that are in the top 20 of online travel sites. Marriott, Hilton and other hotel chains now try to get customers to book directly. The commission charged by Expedia and Orbitz has dropped from 21% to 15% for hotel operators. Smaller hotel operators look warily at the concentration of power in two major hotel online companies, one led by Priceline.com that includes Kayak, Rentalcars.com, Bookings.com, and the other led by Expedia which now includes Orbitz, Travelocity, Hotels.com, CheapTickets.com. The competition is more intense in the hotel bookings business....
