Hello Altiplano,
If you can get your spanish going that`s all the better 4 U.
There are some A320 Captains on commutter sched, it is not official though, after you have seniority you work it out with your boss plus given the A320 rosters we have it is pretty inconvenient.
As far as pay goes, since you have not jet time, you start @ 60% too.
Upgrades are predicted to take 5 years on new hires now (not bad at all for an A320), a while back used to take about 10 years.
I was hired somewhere in between, have been in the 320 for almost 3 years now and possibly I will go to the 767 as FO, if I don`t, they will upgrade me on the 320, if that happens that is cool but, they will keep me there almost forever before going to the 767, A340 or 787 since I did not fly long haul routes before, it is a "catch 22""situation.
But if you can get hired do it, and build time to go to a better place afterwards, after all that is what airlines do with pilots nowdays, they just use you.
Regards,
