I'm not on the company, anyway it's called Sueldo y Rol de vuelo around here, get used to it...
Rol can be adjusted in two ways 5 on 2 off and 10 on 4 off
Pay should be around U$5000 full pay for F/O, low time F/O around U$3600, then would go up in a one or two years term to the standard pay.
70 Ex-Mexicana guys came here, just 12 made it trough screening
Dont forget the license conversion.
