At the early part of the CoviD19 breakout, we needed to re-route our trip from HK to another transfer point due to VN tightening their travel requirements. We changed from a Cathay Pacific flight to JAL through Tokyo. The quick connection (1:25) at Narita in Tokyo was super quick, very efficient. The airline's cabin crew were all very good at their jobs and the food was decent/good. Didn't get much sleep, but the cabin stayed dark enough that many did.
