Ryanair is the latest airline to have its pilots go on strike in a dispute over pay.
Members of the British Airline Pilots Association (Balpa) voted by four to one to back action on a 72% turnout - resulting in a 48-hour walkout beginning on Wednesday, September 18 and lasting to the end of Thursday.
The long-running dispute is largely based on pensions, loss of licence insurance, maternity benefits, allowances and a "fair, transparent, and consistent pay structure".
Pilots are also ready to strike on Saturday, September 21 as well as September 23, 25, 27 and 29.
Earlier this month, British Airways was forced to cancel nearly 1,600 flights on 9 and 10 September after it was left with “no option” as a result of the industrial action called by Balpa.
In August, Ryanair was successful in its bid to prevent a 48-hour strike by pilots after the Irish High Court ruled in its favour.
Announcing the upcoming dates, Balpa General Secretary Brian Strutton said in a statement: “We are clear that we want to settle the dispute and bring about a change in Ryanair for the better.
“Pilots in Ryanair are seeking the same kind of policies and agreements that exist in other airlines – our demands are not unreasonable.
“Ryanair should stop dragging its feet and get back to the negotiating table."
Ryanair responded claiming that it expects all flights to and from UK airports thanks to the efforts of 95% of its UK pilots.
The airline said: "On behalf of our customers and their families we wish to sincerely thank all our UK pilots who do not support these Balpa strikes."
