The European Union moved toward prohibiting Belarusian airlines from operating in its airspace or landing at its airports — a move that would effectively block the country’s air connections to Western Europe — a day after that country’s leader sent a fighter jet to force down a Ryanair flight in order to seize an opposition journalist on board.
Europe’s decision came after the British government said it would prohibit Belarus’s national airline from landing or operating in the country. Both Britain and the E.U. also advised airlines to avoid flying through Belarusian airspace.
Belarus, in eastern-central Europe, is along a major air corridor between Europe and Asia.
The moves came as airlines and lawmakers were trying to find the right way to respond to what was widely seen as a shocking move by Aleksandr G. Lukashenko, the Belarusian president who has clung to power despite huge protests last year. European Union officials are expected to meet on Monday to discuss their options for penalizing the country, which is closely aligned with Russia.
The British government said that it was halting all flights by Belavia, the Belarus national airline, to Britain immediately. “This essentially means no journeys are possible from Belarus to the U.K.,” a government spokesman said.
Earlier on Monday, at least two airlines said that they were diverting flights away from Belarusian airspace as a precaution, but most carriers seem to be waiting to be told what to do by the European authorities.
Lithuania’s transport minister announced that all flights to and from Lithuanian airports must avoid the airspace of neighboring Belarus, Reuters reported. The minister, Marius Skuodis, said the ban would begin Tuesday at 3 a.m. local time.
Ryanair’s chief executive, Michael O’Leary, on Monday condemned the actions of the Belarusian authorities, who ordered the plane, flying from Athens to Vilnius, Lithuania, to land in the capital of Minsk and then arrested Roman Protasevich, a dissident journalist on board, and his companion.
“This was a case of state-sponsored hijacking, state-sponsored piracy,” Mr. O’Leary told interviewers on Newstalk, an Irish radio broadcaster.
Mr. O’Leary, however, said he was waiting for instructions from European Union authorities in Brussels about whether to steer other flights away from Belarus.
He added that it would be an easy matter for his flights to avoid the country’s airspace. “We don’t fly over Belarus much,” he said. “It would be a very minor adjustment to fly over” Poland instead, he added. Ryanair, a discount airline based in Ireland, describes itself as Europe’s largest airline group.
Other airlines, flying shorter routes, are already making changes.
AirBaltic, the Latvian national airline, said that its planes would avoid entering Belarusian airspace “until the situation becomes clearer or a decision is issued by the authorities.” The rerouted flights include ones from Riga, the airline’s home base, to Odessa in Ukraine and Tbilisi in Georgia.
Another airline that flies in the area, Wizz Air, said that it would alter the path of a flight from Kyiv, Ukraine, to Tallinn, Estonia, so as to skirt Belarus.
“We are continuously monitoring and evaluating the situation,” a spokesman for Wizz Air, which is based in Hungary, said.
