Altogether, 2015 was a good year for the US hotel industry. For the month of November, US hotels improved on three key metrics: room occupancy, average daily rates, and revenue per available room, according to STR Global, a hotel industry research firm. Year to date, hotel performance is also up across the board. But in big US cities, Airbnb is making a more noticeable dent in the hotel business. That distribution is important because it means Airbnb is also edging into hotels’ territory significantly more in those cities. Across the US, Airbnb represents only about 1-2% of hotel demand. But in some of those top cities, Bank of America estimates that Airbnb makes up closer to 5-7% of hotel demand. The same is true on the supply side. Nationwide, Airbnb’s entire-home and -apartment listings are thought to make up 2-4% of the overall hotel room supply. But in the biggest US markets, those same Airbnb listings account for an estimated 8-15% of the hotel supply. Get the full story at Quarz
