The 28-year-old, who is now learning to be a paramedic, had submitted a voluntary redundancy at the time.
A source told The Sun: 'Connor felt cabin crew were unfairly targeted. After deciding to quit, he decided to tell the world what he really thought of his job.'
Meanwhile Mr Scanlon from Dunfermline, Scotland, commented: 'I know I shouldn’t have put it on.'
It follows the airline's owners IAG announcing redundancies back in April amid the coronavirus pandemic.

In a statement, it earlier said: 'In light of the impact of Covid-19 on current operations and the expectation that the recovery of passenger demand to 2019 levels will take several years, British Airways is formally notifying its trade unions about a proposed restructuring and redundancy programme.
'The proposals remain subject to consultation but it is likely that they will affect most of British Airways' employees and may result in the redundancy of up to 12,000 of them.
'As previously announced, British Airways has availed itself of the UK's Covid-19 job retention scheme and furloughed 22,626 employees in April.'
