Ola Holidays has been ordered to make clear that adverts for holidays which appear on www.teletextholidays.co.uk are subject to limited availability.
The order came from the advertising watchdog as it upheld a complaint against the company over an ad for £208 which was said to be unavailable.
Woodford Green-based Ola Holidays disputed the claim that the deal was unavailable, saying that it could see no reason why there would not have been availability when the complainant contacted them following the advert appearing in July last year.
Because Teletext was not involved in the booking process, the company said it was unable to advise on whether Ola would have had availability of the holiday on the day the complainant tried to book.
But the Advertising Standards Authority said: “Because Ola and Teletext had not supplied documentary evidence which substantiated that the holiday was available at the advertised price when the complainant saw the ad, we concluded that the ad was misleading.”
It added: “We told Ola and Teletext to make clear that offers were subject to limited availability.”
