WASINC is a good company. on the other hand kungPen STAY AWAY if you can. there are a lot of guys that they are there currently but haven't flown for 4-6 months. reason for it is documentation. i left from kungpen so did about 4 other guys. Actually few more are about to call it quits very soon.
There is o guaranty that you will see the EMB and defenitelly no guaranty for upgrading on the A320 OR 737 OR 747. Accommodations are very poor and dealing with the chinise govermant is a pain. Contact for the chinish worth less than toilet paper. THEY DO NOT HONOR THE CONTRACT and that is a problem. Oh and MESA is pulling out of China too. If you need mor specifics PM me.
