i never did hkg tpr-nrt so others can advise if you can deplane and lounge is 5-7min walk from gate area inside security if you can deplane.
just so you know fare for TPE-NRT-HKG-TPE J is about same as HKG-NRT economy. when i buy this ex TPE route to japan i always take diff.flight numbers for HKG-TPE and TPE-NRT to ensure i get extra status credit/CP... so i always deplane
does anyone know if i get 2 segments credits if i bot cx450 on 2 tickets for respective segments?
