Luxury Card https://x.gd/jXI6n Referral Code: LCAMBJA041 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. 🎫 Flight Information ──────────────────── 【Outbound Flight ①】 ■ Airline: Japan Airlines (JAL) ■ Flight Number: JL225 ■ Route: Tokyo (Haneda) → Osaka (Kansai) ■ Date of Flight: September 7, 2026 ■ Departure Time: 12:35 ■ Arrival Time: Around 14:00 ■ Aircraft: B737 ■ Seat: Economy Class 【Outbound Flight ②】 ■ Airline: Japan Airlines (JAL) *Codeshare flight issued by Alaska Airlines ■ Flight Number: JL60 (Alaska Airlines AS7318) ■ Route: Osaka (Kansai) → Los Angeles ■ Date of Flight: September 7, 2026 ■ Departure Time: 17:45 ■ Arrival Time: 12:30 (Local Time) ■ Aircraft: Boeing 787-9 ■ Seat: Economy Class (2-4-2 configuration, window seat) [Return Trip ①] ■ Airline: Japan Airlines (JAL) *Codeshare flight issued by Alaska Airlines ■ Flight Number: JL69 (Alaska Airlines AS7319) ■ Route: Los Angeles → Osaka (Kansai) ■ Date of Flight: September 9, 2026 (local time) ■ Departure Time: 15:00 (local time) ■ Arrival Time: 18:30 ■ Aircraft: Boeing 787-9 ■ Seat: Economy Class [Return Trip ②] ■ Airline: Japan Airlines (JAL) ■ Flight Number: JL228 ■ Route: Osaka (Kansai) → Tokyo (Haneda) ■ Date of Flight: September 10, 2026 ■ Departure Time: 21:10 ■ Arrival Time: Around 22:30 ■ Seat: Economy Class ■ Fare: 46,000 yen round trip (tax and surcharge included / ticketed by Alaska Airlines) ▼Chapters 0:00 Starting from Haneda Terminal 1 / What is the 46,000 yen round trip error ticket? 1:11 Check-in at the international transfer counter (luggage checked through to Los Angeles) 2:49 Changing mileage from JAL to Alaska Airlines (reason for 100% accrual) 3:41 Ticketing process and how it spread on X 4:39 [Caution] Be careful not to make mistakes when rewriting your mileage number 5:57 Also sold from Osaka and Fukuoka / Regarding seat selection on codeshare flights 7:05 To Kansai Airport on JL225 8:42 Arrival at Kansai Airport ~ Transfer to international flight 10:17 Kansai Airport 4th floor departure floor / I also received a lounge invitation ticket with Alaska Airlines mileage 11:36 Departure ~ To the premium side of the "KIX AIRSIDE LOUNGE" 14:12 Take the Wing Shuttle to Gate 27, boarding 15:48 Comfort of JAL 787 (2-4-2 configuration) / Load factor about 70% 18:13 In-flight Wi-Fi ($16.80) and drink service 19:47 First in-flight meal: Hashed beef / Routine for eating coffee & Häagen-Dazs 22:01 Mid-flight (movie, sleep) 23:20 Summary of the problem of not being able to select seats on codeshare flights 24:24 Second in-flight meal: Omelet rice 25:32 Arrival in Los Angeles, immigration, baggage claim 29:11 Arrival at LAX / Tips for buying error tickets and precautions for extremely tight itineraries 30:34 Going to ride a Tesla Cybercab 31:38 Check-in for return flight at LAX Terminal 4B in 3 days 33:18 Centurion Lounge / Story of cheap air tickets I've bought in the past 35:31 Boarded JL69, lucky seat with an empty seat next to me. 37:36 First in-flight meal on the return flight: Pork bowl 39:52 Second in-flight meal on the return flight: Burger 41:08 Arrived at Kansai Airport and cleared immigration 42:51 Took the last flight from Kansai Airport to Haneda Airport to Tokyo 44:20 Summary: The 46,000 yen round trip was well worth it. ▼Related Videos Tesla Cybercab boarding video: テスラのサイバーキャブで巡るアメリカ・オースティン旅行 #JAL #LosAngeles #ErrorTicket #AlaskaAirlines #CheapAirfare #KansaiInternationalAirport #HanedaAirport #OverseasTravel #ShortTrip #JGC https://amzn.to/4oNHcTs Onoda's first book!
