To clear things up (best I can), I flew from BOG to MDE a few weeks back. The domestic terminal has two security checkpoints, depending on where or who you are flying with. My flight happened to be past the wrong security checkpoint, so I didn't have access to the lounge. Well, I did, but I had to go through security just to use it. I was able to use PP in the new lounge and its quite nice. Downside, beer served in kegs, so you can't take any cans with you.
PP didn't work in Puente Aereo because they said it's only allowed if its not too full... it was ALWAYS full. I used to be able to work some magic and get in anyway, but it wasn't always easy...
