The prices:
I have always resented airfare pricing structures. 3 week advanced purchase, saturday stayovers required, ect. The airline would rather fly the trip with a nearly empty plane thatn sell me a ticket at the last minute for a fair price.
The passangers:
People try to carry to much stuff on the plane and then take too long getting off the plane. One carry-on should mean one carry-on. If your a woman, your purse is that carry-on! If your a business traveler, your laptop or briefcase is your carry-on! I constantly see business travelers carrying 5 or more items/bags.
The food:
you get two choices for lunch, unless you are in the cheap seats in the back of the plane, then you get whatever is left over. "I'm sorry sir, we are out of the chicken breast, but we have a bannana and a slice of meatloaf left for you."
The FAA rules:
It's a major pain in the ass bringing firearms in checked baggage. When you fly with firearms you are usually going to be dealing with panic or confused airline employees who have no idea what to do.
Knives;
Used to be anything under 4". Then they said no serrations, now no knives period. I carry a knife everywhere.
So until the airlines lower their rates, enforce the one carry-on rule, improve service, and allow us to carry pocket knives again, I'm not flying. I'll drive everywhere.
Notice my reasons have nothing to do with terrorism or "safety". Yet the Airline executives will assume that's why I'm not flying anymore.
