Jet2 is suspending flights to Poland. The airline said it was linked to 'current circumstances.
Flights to Krakow will be suspended from March 24 to May 26. It comes as the Russian invasion of neighbouring Ukraine continues to cause bloodshed and a refugee crisis.
Leeds-based Jet2 has said affected passengers would be refunded, Liverpool Echo reports. The BBC reported that the decision was also linked to 'low demand'.
A Jet2 spokesperson said: "Due to current circumstances, we have taken the decision to suspend our flights and city breaks programmes to Krakow from 24th March up to and including 26th May.
"Where customers are affected by any programme changes, we will automatically cancel their booking with a full refund.
"We are planning a phased restart to Krakow from 27th May and we will of course keep customers updated."
The Pentagon has rejected Poland’s offer to give the United States its MiG-29 fighter jets for use by Ukraine in a rare public display of disharmony by Nato allies.
Pentagon spokesman John Kirby said Poland’s proposal on Tuesday to deliver the jets to the US Ramstein Air Base in Germany raised the concerning prospect of jets departing from a US and Nato base to fly into airspace contested with Russia in the Ukraine war.
“We will continue to consult with Poland and our other NATO allies about this issue and the difficult logistical challenges it presents, but we do not believe Poland’s proposal is a tenable one,” Mr Kirby said in a statement.
“It is simply not clear to us that there is a substantive rationale for it.”
