The Ngurah Rai International Airport in Bali remains closed at least until 7AM on Wednesday November 29, 2017, due to volcanic ash cloud from the Mount Agung that erupted earlier.
Passengers that are stranded in Bali should stay put or find their way to Surabaya where there are air links to Singapore and Jakarta. Even if the airport opens for traffic at 7AM on Wednesday it will take some time for the airlines to get their operations rolling and passenger backlog resolved.
This volcanic activity in Bali is almost yearly occurrence and airlines always end up canceling flights due to possible invisible ash clouds even when the airport is not closed. Well. There are way worse places to be stranded than Bali!
