9W 227 halts for 02:30 at BRU where they have their own lounge. It's operated by an A330- a mix of A332 & A333.
The 9W A332 has herringbone layout in J, with 1-1-1 configuration. OTOH, the A333 has 2-2-2 config.
Besides UA and 9W, AI flies a B77W non-stop on the route. This could be an option for you, given that AI is now a *A member.
