Singapore Airlines (SIA) will suspend all its flights to and from Bangkok until further notice due to the security situation, and a lack of operational service staff, at Suvarnabhumi Airport.

The suspension includes those flights scheduled between Tokyo Narita and Bangkok, in addition to flights between Bangkok and Singapore.

In a media release earlier today, the airline advised customers booked on flights in the near future to monitor for news about flights on the Singapore Airlines website. When a decision is made to resume flights, an announcement will be made.

"At this time, given the situation at Suvarnabhumi Airport, it is not possible to say when flights will resume, but it is hoped the situation can return to normal soon so customers can resume their travel plans, or return home," SIA said.

In addition, Singapore Airlines will waive all cancellation and change fees for customers with tickets to Bangkok on Singapore Airlines flights issued prior to Nov 26, for travel up to and including Dec 7.

Customers whose flights are being disrupted should contact their travel agent, or if the booking is made directly with Singapore Airlines, contact any Singapore Airlines Reservations Service Centre. The Singapore telephone number is 6223 8888.
