I forgot to say it is with one world.
All the flights were booked with JL, But first flight is AA, and second is: CX

AA says 16.5 hours is there cut off for holding bags during a layover.

Can I camp out somewhere in landside at night at NRT?

You will arrive and depart from Terminal 2 of NRT, I will limit the information to Terminal 2. The latest information (April 2023) is that you can camp out at B1 basement (train station), 1st. (arrival). and 2nd floor of Terminal 2. 3rd fl. (check-in departure) is closed to the public overnight.

2nd fl. of Terminal 2 has about 50 seats throughout the floor, some against the wall with a table where can do some work. 2nd fl. has the most seats and it is the popular location for people camping overnight. 2nd fl. has Yoshinoya beef bowl restaurant open 24 hrs. B1 basement on the train station level there is a 7-Eleven convenience store open 24 hrs.

During overnight only the center entrance door on 1st. fl. is open for the entrance. All other entrance doors to Terminal 2 will be closed overnight.

At the basement of the parking lot at Terminal 2 (can access through 2nd. fl via a walkway) has Nine Hours capsule hotel if you prefer a bed to sleep in. There are hotels right near Narita Airport with free shuttle bus to the terminal, if you want a room with a bed to sleep.

With a 23 hour layover I would seriously consider taking a train into the city. Narita City has a small handful of 24-hour restaurants. One could ride a little further in toward Chiba City and find a 24-hour internet cafe pretty easily. Or spend a night in Shibuya or Roppongi or Golden Gai...

Coin locker overnight is likely to cost 800 to 1200 JPY depending on size.
Cheapest bus to Tokyo and back is 2,600 JPY
Cheapest accommodation around the airport is likely a capsule at Sora no yu onsen for 4,000 to 5,000 JPY (free shuttle bus for most of the day)

While we're counting aluminum coins, the Keisei limited express train to Ueno is only 2,100 JPY round trip...

I have a day and a half transit between NRT and HND.
Does anyone have any suggestions on what to do?
Also, does anyone recommend luggage delivery from NRT to HND or just lug it around?

I was thinking of going into Tokyo or maybe going to the outlet.

Any remotely useful answer would depend on how you intend to rest (or not) during that time.

Saying that, the one constant in any of the hundreds of choices and variations of choices open to you is that there isn’t a straightforward luggage delivery service available within your time frame.

Not to say that it can’t be done, there is a “man with a van” network and if money is no object, it can be arranged.

But, generally, the takkyubin services only accept deliveries to airports 2 days before

This is when you need to put in a plan of action:
What’s your arrival time?
Departure time?
Do you want to go straight to (am presuming) HND, stash your luggage in locker there and then continue footloose and fancy free in Tokyo, Kamata, maybe even Yokohama or Kamakura.
Sleep, don’t sleep, grab a few hours in a cybercafe or a bath house or grab some daytime shut eye in a love hotel. More hotels than ever have day rates now. Your call.
Perhaps you want to go to a a hotel room with expansive views.
Perhaps you want to cocoon yourself in a capsule hotel.
Do you want to eat as many local foods as possible? If so, how? Izakaya hopping in the evening or at one of the hotels with expansive breakfast or brunch buffets with huge selections of regional specialities.
Perhaps you want the classic “salaryman” Kōbō Abe Boxman experience in one of the country’s more depressing building-code-violating ventilation-lacking business hotel chains.

It’s all there waiting for you, every permutation, at every price point.

Thanks for that information.
One of the main things you helped answer was that it doesnt seem like the luggage transport can do next day delivery for luggage between airports.

The classic approach I was thinking is from NRT to Tokyo, then spend the night around the city and then next day head to HND
However, was thinking if there was other things around HND thats worth checking and it might be cheaper to get a hotel around there instead.

Second approach would be NRT to HND via limousine bus and then check in the luggage and spend the night at HND.
Then next day maybe travel around HND before boarding flight.
I know the HND airport just undergone a huge renovation but was thinking if there are other places around HND.
Thinking maybe the outlet or Yokohama. Was thinking of even renting a car and maybe go to the outlet.

Just wanted to see if people have done something similar and what recommendations they might have.

Kamata (https://www.flyertalk.com/forum/japa...onnection.html see post #13)
Kamata
Don’t know which outlet you mean. There is a big Aeon Mall near Narita Airport. Not obvious to me where you might mean near Haneda. Haneda Airport Garden?
If that’s what you mean, outside of the bathhouse and the breakfast buffet hard to see the draw.
Other places around HND? Kamata

Yokohama? I think it’s a great place to meander around in the evening.

There is the Mitsui Outlet mall in Yokohama Bayside, and there is the further one in Gotemba. Gotemba really requires a car, especially if you don't have a full day. Please note that renting a car requires an international driver's license, not just your home country one. The Yokohama one is not super exciting.

With a "day and half" transit, you have a fair amount of time to fill. Despite all the charm of Kamata, I'd suggest getting a hotel more centrally in Tokyo and see a bit of the city centre and interesting areas. Apart from food and the onsen, there is nothing to really see and do in Kamata.

Another good option is a hotel in Yokohama, I think the Limousine Bus from Narita basically only goes to Yokohama City Air Terminal, but from there it is easy to get to the central locations. The Westin, the Hyatt Regency, Pier 8, Intercontinental, there are many good hotel options and Minato Mirai and China Town can easily fill your time with interesting things.

What are your arrival and departure times?

Tight connection - Klook/private transfer?
 

I didn't pay enough attention to a booking and have a 3:35 minute connection from HND to NRT. AA marketed ticket on JAL flights in J. International to International flights. I won't have any checked bags.

It looks like the train and airport bus schedules are no goes unless there is a very short line at Haneda immigration. Some partial good news is it is a Saturday afternoon so less traffic and being in J I will get off the plane in Haneda fairly quickly. So I think I'm left with taxi or other private arrangement. It looks like taxi is $190 and private van prebooked on Klook is ~$125. Questions -

Anyone have experience with Klook bookings for Tokyo airport transfers? I'm inclined to rule this option out only because if the flight to Haneda is delayed I'll likely be in no rush to get to Narita. If the flight does arrive on time I can just suck it up and pay the $190 taxi.
If the flight is delayed my understanding is it would be JAL's responsibility to rebook me since the delay would be on their metal as opposed to me calling AA, is that correct?
What if the flight is on time but I still miss the connection, will they rebook me or I will need to pay fare difference?
In the case of a rebook do they try to do it on their own metal or will they rebook on a competitor to get to the destination if its the fastest option?
Thanks

The shortest train option is 1h 27m, which is about the same as the bus schedule, though that is probably well padded and likely will take less. The taxi ride should be about an hour. You can make it with the bus/train if the timing is really well suited for your arrival, but yeah unless you are very used to the flow I'd not plan on that as a practical solution.

For the taxi price mentioned, you probably have to throw in another 2900 yen or so in highway tolls, don't know how the Klook pricing is set.

It the flight is late so you can't make the connection, JAL will have to rebook you, for irrops on the travel day, it is always the operating carrier you should talk to. If the flight is on time, and you don't make the connection, they will likely just rebook you, but you'd probably have to fend for your own hotel if needed. Unless you have clearly been wasting the time on detours, then you probably fully have to fend for yourself.

If your flights are on time, I would call an Uber Taxi. You’ll have a reliable rate estimate, and the taxi driver will utilize Google Maps traffic data to route you most efficiently.

An Uber Taxi in Japan is just the regular metered taxi fare plus an Uber uplift. Most taxi companies offer a fixed rate between the airports, but it usually requires pre booking. But the ease of Uber is in the absence of a language barrier in the booking and destination process.
