The carrier is also pushing back the resumption of flights to Cuba, with the Heathrow-Havana route now due to resume in the second half of next year, with cancellations extended to 29 October 2022.
A Virgin Atlantic spokesperson said: “It remains a dynamic time for international travel and we’re continually reviewing our flying and holiday schedules.
“As we consider our longer-term flying programme, we’ve taken the decision to restart our twice-weekly Heathrow-Havana flights in the second half of 2022, when we look forward to returning to Cuba.
