The spokesperson said: "The safety and security of our customers and people always comes first.
"We continue to monitor the situation in Ukraine and Russia extremely carefully following the escalation of conflict, with ongoing dynamic assessments of our flight routings based on the latest situation reports and always following the strict advice set out by the Department for Transport and other global regulators.
"This has included adjustments to our flight planning since December to further increase distance from the Ukraine-Russia border."
