Thanks for the responses. Booked to fly SYD - HND - LHR soon and Japan still closed to tourists also airside transit hotel still closed so a night in the terminal beckons!
Hi
@neils2004 , I did that trip earlier in the year, albeit in J class, but found them to be an amazing airline, very efficient, great food and extremely polite. Had no issues with transit at HND, and laying on a bench in there terminal overnight wasn't that bad. Just be prepared and bring a pillow and a blanket as it gets cold! It felt very safe and secure but not many places open.
There is a paid lounge (if you don't have access) that you can just jag when you arrive as they close at 10pm. You can pay for a shower and a basic lounge access, its worth it. The JAL lounge closes as you arrive normally.
On another note, it took about 2 weeks for my points/tier points to credit to my frequent flyer account (I use BAEC), so if it doesn't show up straight away just give it a few weeks.
If you have any other questions, feel free to ask.
