Tezzer, Im the same as you. And havent missed a flight yet.
Although, Im quite happy to spend an hour sat in a bar having a drink and breakfast/lunch/dinner whatever.
But it helps that I only fly about 14-20 sectors a year. If i flew more than that, as most of you on here do.......I expect I would be trying to cut down my airport time.
I agree with the comments above about what you pay is what you get in this situation. Look at it like buying a car.........Buy a 1 year old BMW from a BMW dealer, expect full help when the exhaust falls off a week later. Buy it from a private seller for 5k less out the classifieds......expect a different service. Bit of a strange comparison I know.
