Analysis-Easter travel warnings pile pressure on European airlines

LONDON/PARIS (Reuters) - European aviation is gearing up for Easter travel disruptions marked by strikes and cancellations, in a major test of the industry's ability to prevent a repeat of last year's summer holiday season chaos.

Strikes have rolled through France, Portugal, Britain and Germany in recent weeks and could cause air travel disruption in parts of Europe through the Easter holidays, officials at airlines, airports and air traffic authorities told Reuters.

"There will be delays. There's no doubt about it," said Steven Moore, who is in charge of air traffic management operations at Eurocontrol.

Details of the delays remain unclear but the warnings illustrate how vulnerable aviation remains to external pressures, despite efforts to avoid a repeat of last year's queues and cancellations.

Airlines are frustrated at the escalation in industrial action after they have worked for months to tackle the pressing problem of labour shortages via better coordination and by staffing up for a potential return to pre-pandemic traffic levels.

"I think it's something that we have to plan for and we're doing our best to try to mitigate that. But it's, of course, very difficult because ... you sometimes get only 24-hours notice," easyJet CEO Johan Lundgren said.

That is unlikely to quell a debate over the European Union's strict passenger compensation rules. Airlines say they have to pay compensation without themselves getting compensated for air traffic delays.

Consumer groups say air traffic control strikes are not new and airlines should be quicker to react and pay compensation.

European consumer lobby BEUC said consumer pre-payments for air tickets should be phased out, especially in times of disruption, as airlines often spend that money quickly leaving consumers struggling for months to get their money back.

The spectre of new delays came as France was gripped by the latest in a series of national protests over pension reform on Thursday.

France's strikes alone have caused thousands of hours of delays so far - sometimes triggering 70,000 minutes of delays in one day, based on data shared by Eurocontrol.

If a flight is delayed early in the day, there is a compounding effect as planes arrive later and take off later in their destination airports, causing systemic issues.

Since March 13, France's civil aviation authority DGAC has almost daily required airlines to cut their flights by 20% to 30% at several airports, including Paris's second biggest hub Orly.
