Question 1

Can I buy extra baggage online after booking?

Accepted Answer

Yes. On domestic routes buy 5-40 kg prepaid tiers and on international routes 1-5 prepaid pieces via the Tianjin Airlines website, Hainan Airlines app/mini-program, hotline 95350 or authorized OTAs, as long as you have not checked in and the purchase deadline has not passed.

Question 2

Where do I buy extra baggage?

Accepted Answer

Buy prepaid allowance on tianjin-air.com (through the checked-baggage / prepaid-baggage pages and the 'Buy now' entry), the Hainan Airlines app or mini-program, hotline 95350, authorized OTA channels, or at the airport check-in counter.

Question 3

When is the deadline to buy extra baggage online?

Accepted Answer

Domestic: before 60 minutes ahead of scheduled departure and strictly before check-in. International: before 180 minutes ahead of scheduled departure and strictly before check-in. Airport counters sell excess allowance until the flight closes.

Question 4

How does the airline calculate extra baggage charges?

Accepted Answer

Domestic uses weight-based tiers (5/10/15/20/25/30/35/40 kg) with counter excess charged per kg by flight distance; international and regional routes use a piece concept (1-5 prepaid pieces) with gate fees per route; any piece meeting two or more excess criteria (extra piece, overweight, oversize) is charged cumulatively.

Question 5

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

Accepted Answer

Online pre-purchase is cheaper on some routes ('线上预购更划算'); the exact prepaid price is shown at sale time. Anything beyond the free plus prepaid amount is topped up at the airport counter at standard counter rates with no discount.

Question 6

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

Accepted Answer

Domestic: each checked piece must weigh 2-50 kg and fit within 40 x 60 x 100 cm. International: each piece must weigh 2-32 kg with linear dimensions of 40-203 cm. At the gate, cabin bags over the free allowance (count, 7 kg per piece or 20 x 40 x 55 cm) are taken as hold baggage for a gate fee.

Question 7

What are the overweight or oversized baggage rules?

Accepted Answer

Overweight and oversize are fee and rule information: a piece that is simultaneously over piece count, weight and size limits incurs stacked charges. Domestic single pieces over 50 kg or 40 x 60 x 100 cm, and international pieces over 32 kg or 203 cm linear, need the airline's prior approval and are handled at the counter, not as standard online products.

Question 8

Do partner-operated or codeshare flights have different baggage rules?

Accepted Answer

Passengers on connecting through-products (e.g. Haitian Wuxian, interline itineraries) and codeshare tickets cannot buy excess baggage online. On codeshare and interline flights, free allowance, counter and gate charges follow the operating carrier, and prepaid baggage is not supported on codeshare flights.

Question 9

Can I get a refund or transfer extra baggage if I cancel or change my booking?

Accepted Answer

Prepaid baggage bought online or via 95350 can be cancelled in the original channel at no extra fee before check-in (cancel check-in first if already checked in; refundable if the ticket was used but the allowance was not). Products are sold per tier and must be refunded in full, not partially; they cannot be changed or endorsed, so re-buy after any ticket change. Refunds are processed within 7 working days of a valid request.

Question 10

Are there any important exceptions or restrictions I should know?

Accepted Answer

You must confirm the prepaid purchase succeeded before checking in and tell counter staff you hold prepaid allowance; if a post-check-in purchase fails, cancel check-in and re-buy. Invoices are issued one day after the flight via the Hainan Airlines app/mini-program (Service Hall - receipts - baggage) or hotline 95350.
