Some airline customers with tickets to Bali could face travel disruption due to the volcanic eruption of Mount Bromo. Volcanic ash in the skies has caused Cathay Pacific and Singapore Airlines to announce that scheduled flights to the region have been cancelled. However, flights from Kuala Lumpur to Bali have not been affected, according to local airline officials.

Air Asia has also said that the ash cloud will not disrupt its itinerary and Tony Fernandes, the carrier’s chief executive, said that the five flights the airline had scheduled today for Bali would be taking off as usual. He added that the airline would be closely monitoring the situation and people with tickets should phone an Air Asia representative before heading out to the airport.

A spokesperson for Malaysia Airlines said that at present none of its services had been affected by the eruption. Singapore Airlines, however, has posted on its website that all flights to the capital of Bali, Denpasar, from Singapore had been cancelled until further notice.

Australian carrier Jetstar said it would be keeping a close eye on the situation and would make a decision whether to fly out of Darwin, Brisbane and Sydney depending on the advice of aviation experts. Spokesman for the airline, Simon Westaway, said the primary consideration was passenger safety.

Virgin Blue customers flying out of Brisbane and Sydney last night had to check into hotels in Darwin as the airline deemed it not safe to continue to Indonesia. All 130 passengers affected by the decision are due to continue their journey later this evening.
