Hotels are undercut by online travel agencies almost a quarter of the time that a property's prices are displayed, according to Triptease.
The UK-based, direct booking widget provider reckons its analysis has shown that the so-called "disparity" accounts for around $1 billion a year in lost revenue for hotels.
The findings were released after looking at 33 million hotel price searches, in order to establish how much (or little) OTAs are trying to get in with a lower price than the property's publicly-available rate.
Triptease CEO Charlie Osmond says:
"Disparity is a sinkhole, costing hoteliers millions. Policing and removing disparities has an immediate impact on direct bookings."
