Xiamen Airlines

A pioneer among Chinese airlines, Xiamen has discovered the delights of tear-off strips to guarantee you an unused bag. Others (like China Eastern) use paper tabs that - if you are careful - you can circumvent by prising the bag open and aiming your waste carefully past the tab.

In the gusset: a bunch of Chinese, with the code ZL 97 2 30785.0, and a phone number: 2220285.

Like the bag above, only the printer has managed to get it centred on the paper. It's on a different grade of paper, too.

In the gusset: a bunch of Chinese, with the code ZL 97 2 30785.0, and a phone number: 0592-2220285 (yes, with an area code).

Xiamen Airlines (new phone number)

The gusset makes the bag: this has the same code ZL 97 2 30785.0, but the phone numebr has changed: 0592-5739796-7

Xinhua Airlines

One of the new breed of chinese bags, complete with a perforated tear-off strip at the top, along with an icon of a pair of scissors (not supplied with the bag: you'll have to smuggle your own on board if you want to cut your bag open).
