text: Thousands of holidaymakers face up to three days of chaos and cancelled flights because of a strike by French air traffic controllers. EasyJet and BA are among a host of major airlines expected to scrap hundreds of flights thanks to the walk-out, which will start at 5am tomorrow and run for 48 hours - with considerable knock-on disruption expected. Experts fear up to half of all flights between the UK and France could be axed, depending on how strongly the strike holds. Delays: easyJet is one of many airlines set to cancel flights over a strike by French air traffic controllers over the next three days (file photo) Families returning from their Easter holidays and those hoping for a last-minute break will be worst affected. EasyJet is cancelling 118 flights to and from France, including 10 which either start or finish at British airports. A spokesman said: 'EasyJet has been advised of planned industrial strike action by French air traffic control services on April 8 and government transport workers on April 9. Like all airlines flying to and from France, we expect significant impact to our flights during this period, including cancellations.' The cancelled services include return flights between Paris Charles de Gaulle and London Gatwick, Paris and Luton, Gatwick and Toulouse, plus flights between Gatwick and Spain. The airline urged all passengers going to France to check the status of their flight online before they travel. British Airways said it was cancelling around a dozen return flights from the UK. A  spokesman said: 'Early indications are that there will be significant disruption for all airlines who fly within, to and from France and who also use French airspace for over flights. 'We are doing all we can to minimise disruption to customers flying to and from France as a result of the threatened air traffic control strike. 'Unfortunately there will be some knock-on delays to other parts of our short-haul network as a result of the strike action, given how much airspace in Europe will be affected. We are sorry for any disruption to customers' travel plans.' Flybe said it was cancelling 16 flights including services to Paris from Manchester, Birmingham and Exeter as well as some flights from Southampton. Adding to the possible chaos, tomorrow is the first day of a new regultion which forces travel operators to check the passports of all passengers leaving Britain and pass on their details to the Home Office. Chaos: Charles de Gaulle Airport, pictured, and other French hubs will be severely affected by the strike . The strike has been called because the French air traffic union says their controllers are expected to retire later than their counterparts elsewhere in western Europe. The walk-out is one of a series planned this month, with more industrial action from April 16 to 18 and another walk-out between April 29 and May 2. Plans for the original strike on March 25 were suspended after the fatal Germanwings crash in the French Alps. European air traffic chiefs at Eurocontrol have also warned of 'a significant risk of disruption', with the number of flights from France's busiest airport down 40 per cent tomorrow and 50 per cent on Thursday. National carrier Air France, based at Charles de Gaulle Airport outside Paris, is expected to be hardest hit. Air France said up to 40 per cent of its medium haul flights to and from Paris CDG will be cancelled. Rregional subsidiary HOP! will axe two thirds of its flights to and from Orly airport, and 40 per cent of services at other French airports. Britain's National Air Traffic Services, which controls the airspace over the UK, said: 'We've spoken to our operational teams and much will depend on the severity of the strike and how the airlines choose to respond in terms of their schedules. 'If it follows previous patterns we can expect a lot of airlines requesting to re-route around French airspace. That shifts the traffic from our usually very busy south coast airspace sectors to the west (Lands End) and east (Clacton and Dover).' A spokesman for the Civil Aviation Authority said passengers affected by the strike would not receive compensation as strike action is classed as an 'unforeseen circumstance' outside the control of airlines. But they will be entitled to food, drink and, if necessary, hotel accommodation. Ryanair said it was cancelling more than 250 flights with more likely, branding the strike 'grossly unfair'. Ryanair is cancelling more than 250 flights, with a spokesman branding the strike action as 'grossly unfair' A spokesman for the budget airline said: 'Ryanair regrets to inform customers that it has been forced to cancel over 250 flights on Wednesday due to a French Air Traffic Control strike. 'Further cancellations and delays are likely and customers should check the status of their flight before leaving for the airport on the Ryanair.com website, where the latest information will be published. We sincerely apologise to all customers affected by this unwarranted strike action and we call on the EU and French authorities to take measures to prevent any further disruption. 'It's grossly unfair that thousands of European travellers will once again have their travel plans disrupted by the selfish actions of a tiny number of French Air traffic Control workers. 'Ryanair said all affected customers have been contacted by email and text message and advised of their options - full refund, free transfer onto next available flight or free transfer onto an alternative flight routing.'
