Budget carrier Ryanair has sounded the alarm over a potential summer of flight chaos, telling UK travel buyers to brace for widespread cancellations if European air-traffic-control (ATC) strikes proceed as planned. Speaking at the airline’s Q3 briefing on 21 January, CEO Michael O’Leary predicted that rolling walkouts—particularly by French controllers—would peak in May and June, disrupting up to 60 % of Western European overflights, including thousands serving British airports.
Ryanair lost more than 1,000 sectors during last July’s French strike and scrapped 933 flights in a single day earlier this month. O’Leary blasted what he called “a broken model”, urging the European Commission to fine ANSPs that fail to guarantee minimum staffing. He also renewed calls for France to permit overflights during domestic stoppages, a concession already adopted by Greece, Italy and Spain.
For UK corporates the warning is significant: Heathrow, Gatwick and Manchester all lie on routings that overfly France even for intra-UK and UK-Ireland services. Travel-management companies (TMCs) are already advising clients to build buffer days into project schedules, secure flexible tickets and stock contingency travel budgets. Airlines can reroute via Spanish or German airspace, but that lengthens journeys and adds fuel costs that may be passed on to corporate contracts.

Should those rerouted journeys suddenly require stop-overs or transits through countries outside travellers’ usual itineraries—think last-minute connections via the Middle East or Balkans—VisaHQ can rapidly organise any additional visa paperwork. Its UK portal (https://www.visahq.com/united-kingdom/) offers up-to-date entry requirements, accelerated processing options and courier support, ensuring corporate travellers stay compliant even when strike disruption forces itinerary changes with little notice.
The looming disruption comes as Border Force prepares to phase out physical departure checks in favour of Advance Passenger Information only—a shift that could make last-minute rerouting administratively easier if carriers integrate the new data-sharing APIs.
Meanwhile, UK business-travel association ITM urged the Department for Transport to coordinate with EU counterparts to safeguard critical trade routes, warning that a third consecutive summer of air-traffic turmoil would undermine Britain’s post-Brexit competitiveness.
