Atlantic 101

Hi all,

I've searched online but struggling to come up with a definitive answer.

If you have a connecting economy flight on Bangkok Airways booked through BA, as a BA Silver would I get lounge access?

And also, if booked independently with Bangkok Airways, would lounge access be granted?

*I did read that lounge access is available when you book a Oneworld round the world type ticket - so thought I'd try my luck!

Thanks for any info!
