Back when I still subjected myself to the security theatre at airports I was told to toss the nearly empty tube of tooth paste I had in my backpack. Why was that? Well, the tube stated it contained 125 ml when new and you're only allowed to bring 100 ml containers so toss it or be denied boarding.

I now travel by train instead of plane. Sure, it takes a lot more time but I can bring however much of whatever I want, I get to sit in a comfortable chair, I have my laptops (etc.) with me and get to work on whatever I want. Sometimes I even meet interesting people. I regularly travel from Sweden to the Netherlands this way, sometimes alone, sometimes with my daughter when she comes home from university or goes back there (she studies in Utrecht, we live in Sweden). Train travel is far from perfect and delays are common but seen as a whole it is a far better experience than air travel. It also happens to be quite a bit less expensive on the routes I frequent.
