Spring Airlines 9C: included 7 kg bag and cabin upgrade

Spring Airlines 9C, distinct from Spring Japan IJ, includes one 40×30×20 cm, 7 kg cabin bag with Saver/Flexi fares. Spring Plus or a specifically purchased cabin upgrade permits one 55×40×20 cm, 10 kg bag, subject to availability. The current contract and 6 July 2026 Chinese clarification agree; older 5 kg articles do not describe this policy.

Measurement and the extra laptop

The published dimensions exclude wheels, telescopic rod and handles. Measure the bag body for this rule, and still consider its complete outside shape for practical storage. One laptop may be carried in addition to the main allowance. This is not a general right to a second handbag, backpack or laptop bag; no universal personal-item dimensions are supplied.

Purchase the right allowance before boarding

A checked-baggage purchase does not enlarge the cabin allowance. Check the exact purchased cabin product and every flight segment. Spring Plus includes 20 kg checked baggage; a Flexi package with checked baggage also includes 20 kg. The calculator uses the included 40×30×20 cm/7 kg allowance. Generic paid or priority mode does not automatically select the separate 10 kg product; verify its larger allowance manually against your booking.

The July notice gives conditional gate handling within a 55×40×20 cm, 10 kg envelope: CNY 300 per piece on domestic/Hong Kong/Macau/Taiwan routes, or CNY 500 internationally. On departures from Jeju or Seoul, oversized or overweight cabin baggage is refused. These are not universal online add-on prices or guarantees that any excess can be accepted. Resolve a larger or heavier bag at check-in.

Batteries, liquids and source scope

The current contract limits power banks to two with readable capacity markings. For 100–160 Wh, obtain prior approval; above 160 Wh is refused. Keep them in the cabin with short-circuit protection. Domestic China flights also require a clear 3C mark and no recalled model. Do not treat the July notice’s 160 Wh ceiling as unconditional permission; confirm the applicable carriage and onboard-use conditions.

The notice limits personal cosmetics to one of each type, containers up to 100 ml, total up to 1 litre, packed separately for inspection. It does not establish that all domestic liquids use an identical international rule. Check departure and transfer screening. The Chinese policy prevails in language conflicts; an older Thai information page has a different upgrade weight.
