A number of strikes across Europe look set to disrupt air travel across the continent in the coming weeks.
In the UK, British Airways cabin crew have voted in favour of striking over jobs and working conditions, which could hit Easter travellers.
Dates have yet to be set for any strikes, with BA managers and Unite leaders trying to thrash out a deal to end any potential industrial action.
Meanwhile, from Tuesday, air traffic controllers in France will hold a four-day strike over proposed merges, which is expected to cause havoc at Charles de Gaulle and Orly airports in Paris.
The French civil aviation authority DGAC could not estimate how badly air traffic would be affected, but last month a similar strike led to half of flights at Orly and 15% of flights at Charles de Gaulle being cancelled.
The news comes in a week where hundreds of flights have been cancelled following a strike launched by pilots at Germany's Lufthansa airline.
