Thai Airways Royal Orchid Plus - Standby upgrade question

I'm flying OSL-BKK on Friday and on to BNE on Sunday on a TG H-class economy ticket.

Does anyone know if this ticket can be standby upgraded for cash to C ?

Potentially yes, at check-in time.

It's not looking too bad at the moment, both your flights are zeroed out in all economy buckets, and are showing C4D4J4. (Translated: economy is full and most likely oversold, whilst there are still a reasonable number of seats in business.) I'd suggest keeping an eye on seat availability, and if it is still looking ok, be at the airport to check in as early as possible and try then.

There's another thread here (http://www.flyertalk.com/forum/thai-airways-royal-orchid-plus/737103-listing-standby-upgrades-prices-thai.html) with typical costs for upgrades for these sectors.
