The error ticket for "Tokyo ⇄ Los Angeles Round Trip for 40,000 yen" that became a hot topic on X (issued by Alaska Airlines, operated by JAL, codeshare flight). We investigated whether it was really possible to fly on it, with a 4-day whirlwind trip from Haneda to Kansai Airport to Los Angeles and back to Kansai Airport to Haneda.
Normally, the fuel surcharge alone would cover the cost, but I was able to enjoy everything: JAL's 787 2-4-2 economy class, lounge access, and two in-flight meals. I hope this information about the ticketing process, mileage registration tips, and potential pitfalls with codeshare seat selection will be helpful to anyone who has booked the same ticket or is aiming for the next error fare.
