According to the Advertising Standards Authority (ASA), 2,370 people complained about the ads, the first of which ran from 26 December 2020 to 3 January 2021 and the second from 4 January 2021.
Both adverts were broadly similar, featuring an image of a syringe and glass vial accompanied by on-screen text, which read "vaccines are coming" and later "jab & go".
A voiceover said: "Vaccines are coming, so book your Easter and summer holiday today with Ryanair… so you could jab and go."
