[1]. There is no flight attendant major at Beihang Headquarters. The flight attendant you mentioned is only a higher vocational major under Beihang Education and Training Center. In Daxing district, it's just a college diploma.
[2]. Here is your website:/,which is the best and most formal flight attendant professional college in China, training flight attendants for major airlines, but it is impossible to be 100% in airlines.
Good luck!
