The most profitable seat on a 787 isn't in business class. It's three economy seats with a $40 mattress pad. I've flown the original version on Air New Zealand. United just figured out the math. A Polaris suite takes the footprint of roughly four economy seats. At $4,000 one-way on a transatlantic route, that's $1,000 per seat-equivalent of revenue. A Relax Row takes three economy seats, sells for $3,000 to $5,000 as a unit, and requires zero cabin reconfiguration. That's $1,000 to $1,700 per seat-equivalent with almost no incremental cost. The margins on a mattress pad and adjustable leg rests versus a lie-flat suite with a privacy door, dedicated galley, and premium meal service aren't even comparable. Air New Zealand proved this in 2011. Called it Skycouch. Same seat. Same concept. Fifteen years of booking data showing parents choose flat over reclined at almost any price. United licensed the design and locked North American exclusivity. The timing maps to a ceiling in their premium strategy. United posted $59.1 billion in revenue last year. Premium cabin revenue grew 11% while economy flatlined. But there are only so many rows you can convert to Polaris before you've hollowed out the cabin. At some point you need the 300 economy passengers to fund the aircraft. Relax Row threads that needle. 200 widebody aircraft. Up to 12 sections per plane. 2,400 units fleet-wide on routes where families will pay anything to let a toddler sleep horizontal for 14 hours. Dynamic pricing at American willingness-to-pay levels on a product Air New Zealand sells for $200 to $1,500. Six fare classes on a single widebody now: Basic Economy, Economy, Relax Row, Premium Plus, Polaris, Polaris Studio. Each tier reframes the next as reasonable. They wrapped it in a plushie because "highest-margin seat in commercial aviation" doesn't fit on a boarding pass.

The basic idea of world models is very old. Optimal control folks were using model-based planning in the 1960s (using the "adjoint state" methods, which deep learning people would now call "backprop through time"). But the real question is what you do with this idea and how you reduce it to practice.
