The airline brand has tweeted about putting its @AerLingus Twitter handle on one of its jets in order to promote the account that currently has a modest 12,000 followers and is operated from 9am to 6pm every weekday.
Aer Lingus is part-owned by Ryanair and is embracing social media soon after Ryanair boss Michael O’Leary criticised labelled social media users "halfwits".
He told Marketing: "Generating noise is now easier because you’ve got all these halfwits on social media ranting and raving, inventing stories, it drives people on to our website. And we don’t spend €50m or €100m on marketing companies to do it.
"The complaint from last summer – where the woman on Facebook who was travelling to Alicante without having printed out her five boarding cards got hit for three hundred quid – she ranted about it on social media, got half a million followers and then the newspapers picked it up.
"We got wall-to-wall publicity from that complaint and we said it was her own bloody fault, too – she didn’t print off her boarding cards."
