Virgin Atlantic has suspended all services between London and Pakistan.
The carrier will continue to operate flights between Heathrow and Lahore until 1 May and to Islamabad until 9 July.
A Virgin Atlantic spokesperson said: "As we continue to ramp up our flying programme in 2023, we’ve taken the opportunity to review our entire network and decided to make a few changes.
"Since commencing operations in December 2020, we have been proud to offer choice for customers travelling between London and Manchester in the UK, and Islamabad and Lahore in Pakistan."
The airline will now communicate to any customers due to fly after these dates to provide options, which include rebooking, where applicable, or a full refund.
