Advertising watchdog ASA has ordered EasyJet to withdraw an advert claiming its flights on some routes are up to 65 per cent cheaper than British Airways’.

The Advertising Standards Authority made the call after a complaint from BA.

The ad promotes seven European destinations including Gibraltar, Alicante, Malaga, Ibiza, Malta, Faro and Majorca.

BA head of leisure sales Adam Daniels, said: “EasyJet can’t add up and they can’t get away with misleading ads. The fares quoted were not correct and none of the quoted savings amounted to 65 per cent.”

In its response to the ASA, EasyJet said it had been unable to trace the relevant substantiation for the ad, due to human error.

The ASA concluded: “The ad must not appear again in its current form. We reminded EasyJet to hold substantiation for their claims and to ensure that savings claims did not exaggerate the extent of any saving to consumers.”
