Constant-Currency Average Daily Rate Growth
2.0%
In the second quarter of 2026, our global average daily rates ("ADRs") on a constant currency basis were approximately 2% higher than the prior year primarily driven by higher ADRs in Europe and the U.S. Our global ADRs were not materially impacted by changes in regional mix in the second quarter of 2026. The year-over-year increase in total gross bookings for the six months ended June 30, 2026 was due to a 6% increase in room nights, about 4% positive impact from changes in foreign currency exchange rates, approximately 2% higher constant currency ADRs, and a positive impact from the growth in flight gross bookings.
