Airline carrier Flybe has been forced to drop a "massive sale" advertising campaign after "misleading" customers over participating airports.
The Advertising Standards Authority (ASA) ruled that the low-cost regional airline had failed to make clear in its 10-million-seat January sale which airports the deal applied to.
The advert used earlier this year featured 70 destinations included in the deal, along with their corresponding prices.
A complaint was made, questioning whether the advert was misleading because it did not make clear to which departure airports the advertised prices applied.
Flybe said the prices and information featured in the advert were correct.
The ASA ruled that the advert must not appear again in its current form. It also said that in any future ads Flybe must make clear whether the prices apply to all, or just some, of the seats on those routes.
"We therefore considered that the ad was ambiguous and likely to confuse readers as to the nature of the flights and prices on offer and we therefore concluded that the ad was misleading," ASA ruled.
Following the complaint, Flybe became concerned about how it could be misinterpreted by the public and had it withdrawn and redesigned.
