Avianca Pilots are on strike now and managemnt is looking to hire outside contractors to fly the routes.. or so I heard. I don't know too much about Avianca El Salvador, (formally Taca I guess?). If it's Avianca, I think the same minimums apply.. 250tt IR, and CMEL.. asuming you are Colombian or native from El Salvador. Your best bet is to check out pprune.com forums or Aviacol forums. Pay is low, around 2K USD per month.. upgrade can take 10+ years or whenever they feel like it. Also I think you have to pay to get your FAA certificates validated in the country or something along those lines. Hope that helps, let me know what you find.
