From this page ... https://www.thaiairways.com/en_AU/ne...schedule.page?Flight Schedule Adjustments from 28 Oct '18... Due to aircraft maintenance and rotation across the network, we're making some changes to the Australia/Thailand schedules and to other destinations across the network.
If you're booked and ticketed via a travel agent, please contact them for assistance with your booking.
Brisbane/Bangkok schedule will be reduced to 4 flights weekly
Sydney/Bangkok schedule will be reduced to DAILY flights
Melbourne/Bangkok schedule will be reduced to 11 flights weekly
Perth/Bangkok schedule will be maintained DAILY with an aircraft change to A330
