Heathrow hotels saw their profits fall in February despite a 5.5% rise in the number of people travelling through the airport.
Profit per room at nearby hotels fell 4.3% as a result of lower occupancy and higher costs.
The hotels achieved a two percentage point increase in average room rates but this was not sufficient to offset a 1.7% fall in room occupancy, according to HotStats UK Chain Hotels Market Review.
Revenue per available room for hotels at Heathrow fell by 0.2% to £57.21. There was a fall in both individual leisure and group leisure volumes, said HotStats.
The hotels did achieve a 0.3% rise in total revenue due to a 2.1% increase in food and beverage takings, but this was wiped out by a 5.5% rise in salaries.
