A complaint by easyJet against a Lufhansa advert for £59 flights to Europe has been upheld by the advertising watchdog.
The Advertising Standards Authority banned the advert after finding it to be misleading.
The ad, published in April and May, promoted flights to Europe but in fact applied to six destinations in Germany from the UK.
EasyJet had queried the availability of flights at the advertised price and the conditions involved in obtaining the fare.
The ASA said that consumers would expect the fare to be available for flights from the UK to a range of European countries.
Making its ruling the ASA said: “The ad must not appear again in its current form.
“We told Lufthansa to ensure they held data demonstrating sufficient levels of availability for advertised fares on each qualifying route, and to make clear any significant travel periods for which availability was limited.”
