What is the type of business class seat Thai airway use to service BNE?

What is the type of business class seat Thai airway use to service BNE? I know they use B777-300, seat guru says it's the staggered lie-flat as seen on their A380, but I've read reports that they use the old angle lie flats with 2-3-2 configuration.

I know TG is know for last minute aircraft swap so it is really a draw of luck. But I would like to know what is the "normal" aircraft/seat type they use to service Brisbane.

It's normally the staggered seats (this is also what they advertise in Brisbane), but like you said they're more prone to last minute changes than a backflipping Australian backbencher.

Thanks! I know it's unreliable, but given that most other airlines servicing BNE uses angled lie flat, at least there is hope. This makes TG the 4th best business class ex-BNE (behind CX, EK A380, EY), and second best Asia bound. 

Do not discount Qantas. When their refitted A330 start plying international routes (including ex-BNE) they'll be a great option, especially with Etihad pulling their SIN-BNE route next year in favour of a direct AUH-BNE-AUH flight.

Peter - agreed on the refitted QF A330 - am  very much looking forward to that -  does anyone know when the A330 fleet will be completed (for complete reliability!) Is it mid 2015? or later?

Of course there are a lot of changes that I am looking forward to in 2015.

Once EY started their 787, their new business class is arguably the best J product out of BNE surpassing CX. (It's open to debate, as we haven't seen the new "Studio" product in flesh).

Once Virgin refitted their 777, it will also be up there competing for number 1 spot, especially now they offer daily service to LAX. 

QF A330 is something to look forward to, although with the way Qantas has been treating BNE, my hope is not too high. Most likely after SYD and MEL gets regular service on the new A330, and if there is left over, then QF will probably give it to BNE.
