I flew United back home this weekend, and already the flight sucked since they overbooked Economy Plus, I'm too tall to see the TV monitors and the audio/video was out. So I complained, along with the guy next to me. The flight attendant said she'd look into it.
Then, flying on the way in - we hit turbulence. And I'm a travel warrior; I fly all the time and turbulence almost never bothers me. Here, I was scared for my life. I had a window seat and it looked like I was stuck in a washing machine, with the plane rocking back and forth and dropping thousands of feet in altitude in a matter of seconds. The entire plane started screaming, and the flight attendants got spooked, crouched in the aisles (holding on for dear life) and starting talking to themselves into a panic.
Touchdown even seemed pretty dicey, but I made it back to the D.C. metro area safe and sound, and for my awesomely horrible flight experience, United will be sending me a free travel certificate.
So if you want a free ticket, tell your pilot to fly into sheer winds.
