Small, personal and you are know by name not by number
Old Aircraft, No Work Life Balance, No Network, No Schedule, No Destinations, No future
They do not speak English, they do not like nor accept (literal) foreigners, they are JAL employees on assignment to Spring, so they do NOT care they just want to go back to JAL main line. A real and absolute waste of time.
No point on joining Spring, (nor Skymark) since you will have no Work Life Balance, let alone make money or have time off... they do NOT offer Commuting and if they did some time ago, you fly Economy. Japanese is official language and those few who speak English inside the company do it bad and wrong, so a lot of misunderstandings . Japanese prefer Japanese by all means, YOU Foreigner are NOT welcome, you are just needed for work and therefore you will be just TOLERATED. Plenty of job outside the Island, think not two or three time before coming here.
