Is there a way to work out which gates my flight will use in advance? I'm worried about this 60 minute connection.

BA282 arrives from LAX at 10:55 on an A388. I believe this means a T5C arrival.
BA308 departs to CDG at 11:55. I'm not sure which terminal 5 sub-terminal this will depart from

Hopefully the departure flight is near a lounge, since I hold oneworld Sapphire.
