Asia based online travel agency Zuji has admitted cash flow difficulties as IATA suspended its license to issue tickets.
The company acknowledged it has outstanding fees to pay to IATA but expects to settle these.
However, both its Singapore and Hong Kong websites are currently down and it is accepting no new bookings at the moment.
The current closure is down to a new website revamp, it claims.
"We expect to resume our service with our new website in Q1 2019" it says.
One of the original Asia based OTA pioneers, Zuji has changed ownership a number of times since launching in the early 2000s.
It was once owned by Travelocity and later Webjet.
The Straits Times reports staff were cut in the Singapore office prior to the closure, with speculation that if the company survives, it will likely only reopen in Hong Kong.
