The Advertising Standards Agency is investigating adverts by Norwegian Air Shuttle (NAS) following a complaint from easyJet, which claims they are misleading as the NAS flights on offer were not available at the advertised price.
The agency agreed that NAS advertising has been misleading when it promoted a three day sale to the Algarve, Nice and Palma from £10 one way including taxes, because it was only applicable to the outbound leg of a return journey and flights leaving from Gatwick.
The watchdog said: "We considered that, while the ad made clear that the price was applicable only to one-way bookings, the requirement for this one-way journey to originate from London Gatwick Airport was a significant condition of the sale promotion and therefore constituted material information on which consumers would base their decisions.
"Given that the web page did not expressly state this information or direct the user to another page where it was prominently stated, we concluded that the ad was likely to mislead and had breached the Code.
