Question 1

Can I buy extra baggage online after booking?

Accepted Answer

Yes. Log in on loongair.cn and buy prepaid baggage under Extra Baggage Purchase, or scan the homepage Baggage Purchase QR code to buy in the WeChat mini-program.

Question 2

Where do I buy extra baggage?

Accepted Answer

On the loongair.cn homepage under the Baggage Purchase tab (scan the QR code for the WeChat mini-program), or after logging in via the extra baggage purchase page; excess fees can also be paid at airport check-in counters.

Question 3

How does the airline calculate extra baggage charges?

Accepted Answer

Domestic excess is weight-based: excess kilograms multiplied by 1.5% of the highest direct adult economy one-way fare on the travel day. International and regional routes use fixed per-piece fees (CNY 1,000-2,000) for extra and overweight pieces, charged cumulatively.

Question 4

Is it cheaper to buy extra baggage online in advance vs at the airport?

Accepted Answer

The online Baggage Purchase channel is advertised as the lowest price network-wide, but no fixed online-vs-airport discount percentage is published.

Question 5

How many extra bags can I buy, and what are the bag limits?

Accepted Answer

Each checked piece may weigh at most 50 kg on domestic routes and 32 kg on international and regional routes, with max dimensions 100 x 60 x 40 cm; heavier or larger items must travel as cargo. Carry-on is limited to one piece: 5 kg domestic, 10 kg international and regional.

Question 6

What are the overweight or oversized baggage rules?

Accepted Answer

Overweight pieces (over 23 kg up to 32 kg) and extra pieces each incur fixed per-piece fees on international and regional routes, charged cumulatively. Oversized items beyond 100 x 60 x 40 cm are carried as checked baggage or cargo per the checked baggage limits.

Question 7

Are there any important exceptions or restrictions I should know?

Accepted Answer

An over-limit control notice applies to oversized, extra-piece and overweight baggage: passengers should check such baggage in advance at the counter. Some promotional (low-carbon economy) fares include no free checked allowance and require purchasing prepaid baggage.
