Flying across the Pacific with a second airline afterward? The long-haul bag allowance may not follow you onto a separately booked flight.
Start with your itinerary
- Write down your first and final airports, plus any stopover or separate ticket.
- Check which airline actually flies each leg, even if a different name appears on the booking.
- Find the fare you bought and the dates you booked or changed it and will travel.
- Count each traveler’s included bags and benefits, then measure the packed bags.
- Compare the charge and currency shown before you pay online and at the airport.
Why a familiar fee may not apply
An airline’s domestic fee can be useful background, but it may not be the price for this route. Open the policy for your destination and check the amount shown in your booking before you pay.
Where the price can change
A U.S.–Asia trip can use piece-based international allowances, followed by a separate low-cost ticket that uses a weight or purchased-bag product. JAL and ANA do not share identical size and excess tables. Jetstar also has a future cabin-bag change beginning in 2027 for specified JQ flights, which cannot be applied to a 2026 connection.
| Carrier or connection | Question to ask |
|---|---|
| JAL / ANA | Different excess size and weight treatment |
| Jetstar / ZIPAIR | Separate fare product and cabin weight purchase |
| Air Canada | Long-haul Basic/Standard change has a May 2026 ticket boundary |
A trip example
A U.S.–Japan traveler has a JAL long-haul flight and a separately purchased low-cost onward leg. Measure the suitcase against JAL’s published dimensions and then check the onward carrier’s smaller or differently priced allowance. Do not transfer the long-haul free pieces by assumption.
