Jet2 said it will keep customers updated once it receives further information about the strike action, but stressed that passengers arrive at their departure airport at least two hours before their flight time to help minimise delays.

The airline said: “Currently, all flights are planned to operate as normal. In the event of any flight delays, further information can be found by using the above search panel by entering your flight number or route. As a reminder check-in desks will close 40 minutes before your scheduled departure time.

“Rest assured, in the event of flight disruption our dedicated Operations teams are always working hard behind the scenes at our UK-based HQ to get you on your way as soon as possible.”

The strike in Portugal is only currently expected to impact flights travelling to and from Lisbon Airport according to the airline.

The airline added: “At present, we believe this to only have a potential impact at Lisbon Airport. We are awaiting an update on the proposed impact in Faro Airport (The Algarve) and Madeira (Funchal Airport).”
