Transited through HND with no issues yesterday. Flight from BKK, they escorted transit passengers as a group from plane to security checkpoint. Only had one scanner open, so took 20 minutes or so to get through. After security you’re dumped into terminal and free to move around. JL Lounge had just opened, we were 3rd and 4th person to enter, was kind of eerie with all the staff standing around waiting for something to do until more people came in. You scan QR codes to order food or reserve a shower.
Duty free didn’t open until 9AM, but grabbed some whiskey once it did.
