The chief financial officer at travel conglomerate Cendant has told analysts that blending online travel business Ebookers into Cendent's business has been "a more difficult integration than anticipated", the Financial Times reported.
In a teleconference yesterday Ronald Nelson said: "We are working as fast as we can to implement the Orbitz technology. We are putting as much of our hotel content as we can on that platform.
"But the platform cannot support substantially more content. You're sort of chasing your tail."
Despite what Cendant refers to as "content and functionality" problems, the company expects the service to be fully operational by mid-2006.
Cendent, a rival to Lastminute.com, has spent £1.5bn in the past two years buying online travel agencies to build up its portfolio, including US number two online service Orbitz.
Cendent has announced that it is to split the company into four separate businesses: travel, real estate, hotels and car rental.
