Overstayed Tourist Card in El Salvador?

I had a similar problem in Nicaragua. They really didn't do anything. They said it was fine and I was on my way. However, sometimes they do charge you a small fine for staying around, but it should not be drastic. Sometimes people don't even notice! In Nicaragua, they don't ask to see your tourist card after you obtain it, well, not when you check in anyway. My umption is that they won't do the same for you in El Salvador either. I wouldn't worry too much if I were you. I'll also run on the umption that you're flying with TACA. I wouldn't worry bro. Take it easy and enjoy your flight!
