Dear CXagents user, Read more from our latest 'Newsletter'.
Due to the current security situation in Colombo, Sri Lanka, Cathay Pacific has decided to suspend all services until further notice.
Safety of passengers and crew is a top priority at Cathay Pacific and a careful assessment of the situation will be made before services are resumed.
All fares to or from Colombo are therefore withdrawn from sale until further notice.
Passengers holding reservations will have already been reprotected.
Please contact Cathay Pacific if you have any further questions.

While non-committal, it does sound CX may let go of CMB altogether. I still haven't heard of CX-CMB (been too busy) but if they aren't issuing any tickets from CMB, then I'm going to change my HKG-BKK to somewhere else.
