StarFlyer (IATA 7G) is a Japanese carrier flying out of Kitakyushu, Tokyo Haneda, Fukuoka, Nagoya and Osaka, plus an international route to Taipei. Unlike a budget airline, StarFlyer is a single-class full-service operator — every seat is a wide leather seat with extra legroom, and a generous free checked baggage allowance is included on every ticket. There are no stripped-back “light” fares that remove your bag, so the allowance below applies to standard tickets regardless of how cheaply you booked.
The headline figures: one free carry-on plus a free checked allowance of 2 pieces at 23 kg each on domestic Japanese flights, and 30 kg total on international (Taipei) flights. All figures verified against StarFlyer’s official English-language baggage pages in 2026.

What you actually get on a cheap fare
What you get at a deal price: StarFlyer is one of the rare carriers where booking the cheapest available fare costs you nothing in baggage. Because it runs a single all-economy product with no “light”/”basic” fare tier, even a heavily discounted ticket includes a free carry-on (up to 10 kg) and a free checked allowance — meaningfully more generous than a Japanese LCC like Peach or Jetstar Japan, which charge for every checked bag.
For deal-hunters this means the advertised fare is close to the real all-in cost: a domestic StarFlyer ticket lets you check two 23 kg bags for free, and the Taipei route includes 30 kg free. There is no upsell needed to bring a normal suitcase, which is unusual at promotional prices.
Oversize, sports & special items
Oversize and heavy items: On domestic flights a single piece may not exceed 45 kg or 292 cm in total dimensions; on international flights the per-piece limit is 32 kg, with a 100 kg total cap per passenger. Anything above 203 cm on international routes must be arranged in advance with StarFlyer’s call centre.
Sports equipment and instruments: Bulky items such as golf bags, skis, surfboards and musical instruments can be checked within the standard size/weight allowance, or carried in the cabin by purchasing an extra seat / cabin-baggage service if fragile or oversized. Fold-up strollers and infant carriers are checked free.
Batteries and restricted items: Spare lithium batteries and power banks must be kept on your person, not in overhead bins or checked baggage. Pets cannot be carried in the cabin or checked on international flights.
Children: Infants and children without their own assigned seat receive a reduced free checked allowance of 10 kg on international flights.
