The only experience that I have of being on a TU-154 was a bad one. It was substituted in for our Air 2000 757 (Yes, it was a few years ago) and had the feel that it was held together with sticky tape! Add to that the surprise of steam of some sort coming down from the roof panels during flight and you can begin to imagine what most people were thinking.
But hey, it got us there safely which is what a lot of these things do all over the world every day.
