They are hiring for sure. I got an Invitacion e-mail to start the interview process from Claudia Moreno Couple of months ago even thoung I decided not to continue with the process I think Avianca is one of the best airlines to work for now days.
AviancaMD83 is absolutly right about everything. And been 100% fluent in spanish and have perm residency it is and should be a minumin and very essential requirement. You need to be a least permanent resident and be fluent in English to Work in USA anyways.
And yes Avianca it still a family when it comes to co-workers I know many Avianca pilots and I flew on them many times in uniform and it is always great expirience.
MDT06 best of the lucks and dont worry about the polygraph test. I hope you are not planning to lie in your interview anyways. Did you go to school in New York??? SUNY????
