Hilton expects the second half of 2019 to be similar to the first half, with consistent RevPAR growth in the U.S. and slightly softer RevPAR growth elsewhere.

Europe led regional RevPAR growth with a 5 percent year-over-year increase for the second quarter, while U.S. RevPAR grew 1 percent year over year in the second quarter, compared with 1.8 percent for the first quarter.

Group business was strong in the first quarter, and Nassetta said the third quarter also is showing strength. That leads the company to expect healthy group business RevPAR systemwide for 2019.
