InterContinental Hotels Group, one of the world's largest hoteliers, posted a 5.9% rise in first quarter global room revenue, delivering growth across all of its regions.
IHG runs over 4,900 hotels under brands such as Crowne Plaza, Holiday Inn and InterContinental.
It said the rise in global revenue per available room (RevPAR), a key industry measure, was led by a 6.6% rise in its core US market where it has benefited from record demand and weak supply.
North America as whole grew 6.2%, while solid growth in the UK and Germany helped RevPAR rise 5.8% in Europe.
Its Asia, Middle East and Africa region posted a 6.2% rise, while RevPAR grew 2.4% in Greater China, five percentage points ahead of the market which has seen business suffer from government austerity measures.
IHG's rivals Marriott, Starwood and Hilton all delivered similar RevPAR growth in North America in the first quarter.
The company said it had achieved its highest first quarter for hotels signings in seven years.
New room openings were also the highest for five years, up 4.9% year-on-year.
The group, which in February posted a 10% rise in 2014 profit, has in recent weeks been mentioned in media reports as both a possible bid target from a US rival and as a potential suitor for Sheraton operator Starwood Hotels & Resorts Worldwide, which is exploring "strategic alternatives".
