Emirates and Etihad Airways were resuming limited flight schedules to key global cities from their United Arab Emirates hubs on Friday, though the threat of missile fire piled pressure on airlines as they scramble to accommodate travellers, reports Reuters.

Britain’s first repatriation flight from Oman landed at London’s Stansted Airport early on Friday after being rescheduled due to operational issues, including delays in boarding passengers.

Abu Dhabi-based Etihad said on Friday it would resume a limited flight schedule through March 19. The flights will operate to and from Abu Dhabi and around 70 destinations including London, Paris, Frankfurt, Delhi, New York, Toronto and Tel Aviv.

Dubai-based Emirates said late on Thursday it was operating a reduced flight schedule to 82 destinations including London, Sydney, Singapore and New York until further notice, and customers transiting in Dubai would only be accepted if their connecting flight was operating.
