Hey all, I’m arriving at SGN, J class on VN50 from London, ETA 0610 on a Sunday morning. I’m not clear if I get fast track immigration with J ticket (evidence suggests not, but the VN chatbot suggests I do), or whether queues will be big enough at that time of day/week to make paying for the premium arrival service worth it (not that it’s expensive!).

I’m flying out of SGN at 1100 on a Wednesday, in regional Premium Economy to DAD. Is it recommended to pay for fast track?

TIA 👍
