Cancellation, delays and hours-long queues are already having an unavoidable impact on summer travel across Europe.

Sweeping job and pay cuts during the pandemic are behind much of the disruption. But it isn’t just passengers that have been affected by staff shortages as now, unions across the industry are calling for strikes over working conditions.

Europe’s low cost airlines are likely to be among those worst affected by the upcoming staff walkouts.

Last minute cancellations and general disorganisation at easyJet have even led unions to claim crew members face a “serious safety risk,” unwillingly working on days off to prevent further disruption.

When are Ryanair workers striking?

Ryanair staff are planning to strike across a number of European countries in June and July.

In Spain, cabin crew unhappy with working conditions and pay are walking out on 24, 25, 26 and 30 June as well as on 1 and 2 July.

Crews from Portugal are also demanding better working conditions for staff and will be on strike on 24, 25 and 26 June.

Trade unions in Belgium say they have been forced to take action as Ryanair is not respecting labour laws. As a result, they are planning to walk out from 24 to 26 June. Brussels Zaventem Airport already had to cancel all departing flights on Monday during action from security staff.

Italian staff have called for a 24-hour strike on 25 June, joining their colleagues in Spain and Portugal.

And in France, unions have threatened action on 25 and 26 June with several airports expected to be affected.

When are easyJet workers striking?

EasyJet cabin crew based in Spain will go on strike for nine days in July, according to the Unión Sindical Obrera (USO).

They will walk out in three phases from 1 to 3, 15 to 17 and 29 to 31 July - just as the summer holiday season starts.

Flight attendants are protesting low wages, demanding a 40 per cent increase in their basic salaries. USO says it represents around 80 per cent of the 450 easyJet staff based in Spain and hopes to reach an agreement to avoid strike action in the first place.

When are British Airways workers striking?

British Airways (BA) ground and cabin crew voted last week on whether to back industrial action over wages.

Unite, a union which represents around 16,000 staff who work for the UK airline, says there was a 97 per cent majority in a consultative ballot about strike action.

It added that thousands of experienced workers had been dismissed during the pandemic leading to a shortage of check-in, loading, baggage handling and cabin staff.

There are no dates set yet as it will have to go to a full industrial action ballot before staff agree to strike. It could, however, lead to further travel chaos for BA passengers this summer.

When are SAS workers striking?

Around 1,000 Pilots from Denmark, Norway, and Sweden’s flag carrier, Scandinavian Airlines could walk out in late June over wages and cost-cutting measures.

They are currently in talks to try and prevent the industrial action but Danish pilots could go on strike from 24 June. They may wait until 29 June when Swedish pilots will be able to join them as they are limited by local regulations.
