Help with 12 hour flight NY➡️Hawaii

Hi all! I’m a FTM starting to plan for a trip from NY➡️Hawaii and could really use some pointers for the 12 hour flight😬. Our LO will be 9 months old and is currently a very good sleeper (3 good naps and sleeps 7p-7a)but needs a blackout room, sound machine, and zippadee sack. We bought him a seat and extra leg room row but I can’t see him sleeping in his car seat for more than a nap.

😴 Any sleep aid suggestions would be so appreciated! 🤷🏻‍♀️ right now leaning towards finding a travel bassinet/stroller but

👎🏻can’t find anything long enough (he’s 7 months now and 30” long)

👎🏻can’t find one with a black out cover.

👉🏻looking at the bedbox ( https://jet-kids.com/product/jetkids-bedbox/ ) but pretty expensive, worth it? Still doesn’t solve black out situation

👉🏻 there’s also this? Which is a cheaper maybe not so reliable option to the bed box? https://www.amazon.com/dp/B06ZYSKSZ4/ref=cm_sw_r_cp_api_i_kdnYDbBVE9FZV

🧸 Also looking for suggestions to occupy our little mr. moveit on the plane

(I found a blog post on TCB but it only covers what to do when we arrive there.)

Thank you all so much!
