Abu Dhabi's Etihad Airways is asking cabin crew staff to take paid leave, according to an internal email seen by Reuters, as the rapidly spreading coronavirus dents global travel demand.

A spokesman for Etihad, however, denied such an email had been sent.

The company is asking cabin crew to take paid leave between April 6 and May 5, according to the email, which does not mention the virus. It did not give a reason for the proposal.

"This is a great opportunity to take some time out or rest, relax and celebrate with family and friends. Leave slots will be available [...] in blocks of six, 12, or 18 days," the email said.

Priority will be given to those who submit longer date requests, it added.
