Be careful that AA is cancelling some HND flights in March 2023 - I don't know why - it may be isolated and was just my flight. I booked four biz tickets DFW to HND the second week of March 2023 and they just cancelled the flight and are now routed DFW-NRT. Thankfully, they had space.. I don't know what they would have done if not because we have no flexibility to fly a different date. Unlikely to affect you, but just in case.
