Juneyao and Spring Airlines
Hello, I am a little late to comment here but have some current information. I have not persoanlly worked at Juneyao or Spring Airlines but have some friends that have.
They left the airline in the employment process and were good pilots currently employed at another chinese carrier. They speak negative about both airlines and tell others not to go there.
Seems there is some sort of riff and politics which could end up leaving you in the cross fire.
I would try more stable carriers if it were me.
Good Luck,
On Final
