There is a priority line for first/business at HND. In J on DL you'll get that. Usually I'm through in about 5-10 minutes if I forget to take off my belt (metal detector has been hit or miss). Immigration has been smile for the camera and get waved through by the desk. No more than 15-20 minutes from leaving the check in desk to into the concourse. Experience the last couple of times have been DL, JL and AA. I haven't been though HND on UA or NH since before COVID/Security Remodel so I can't speak to that side.
