Hi,

New to the site - hope you can help.

I'm in the process of booking a OW Explorer economy ticket, which includes a Bangkok-Sydney routing (departing and booking in London). There was no availablity for the flight I wanted (nor for 2 weeks afterwards!) in economy class, so I got BA to put it through as business class for that leg (Club World, D). From what I can understand of the rulesheet, this incurs a $300 charge, but thats it, no other fees to pay.

Can someone confirm whether or not this is true? The sheet says for a LHR-SYD upgrade its $450, but for everything else its $300. I'm pretty sure it won't be treated as LHR-SYD, as I'm actually going LHR-HKG-BKK-SYD, all with at least 24 hours between them. I still don't get how its only $300 to upgrade to business class on an 11 hour flight, hence why I'd like some confirmation.

Thanks!
