The budget airline's CEO has said France's strikes due to President Macron's pension reforms and the on-going conflict are all set to impact the busiest time of year for travel, with delays anticipated.
Speaking at a press conference this week, he said: “The French usually wait until about March-April to start going on strike.
"This year they are starting on Thursday because they are not happy with (President) Macron’s pension reforms.
"The first people to man the barricades are the French air traffic controllers.
“The real pressure will be on Germany because of the situation in Ukraine.
“Most of southern Poland has been closed off for NATO exercises, so everything going north-south from the Baltic states down to Greece and Italy now has to fly around Germany.
“All the long-haul stuff going to Asia now has to fly down around Germany and across Romania, out over Iran, because they can’t fly over Russia.
“So there is real pressure on Germany, northern Italy, those kinds of corridors there and that’s going to be a challenge.”
