Accessing SIN OW lounge when flying BA
Possibly asked already elsewhere, although my google search returned no results for this...
Anyway the question is: I am flying from SIN to LHR on a BA flight, can I enter the CX lounge at T4?
As I know T4 is fully automated I guess my BA boarding pass would not allow me in, but I was thinking if once I am in T1 I can then use the skytrain + shuttle combo to reach T4 having already passed immigration & security and enter the CX lounge (which seems open to all OW passengers according to OW website).
Thoughts?
