OTA Insight's "The North American Hotel Parity Report" examines rate-parity trends for second-quarter 2018, and shows there are significant parity-loss issues marketwide, with independents and local chains facing losses: 46 percent of tracked shops in comparison to 33 percent for major chains.

A significant majority of parity loss from OTAs was from rates displayed 0 percent to 15 percent lower than brand.com rates. Issues coming primarily from non-contracted OTAs being out of parity - 24 percent in the case of major chains and 41 percent of independents and local chains - suggest non-contracted OTAs are the biggest contributors to parity loss.

OTA Insight investigated the common causes of the losses and found top-line parity figures have stayed more or less the same, suggesting a consistency in rate-parity issues.
