Neither, really. I don't love it (it's such a pain having to get their so early, deal with luggage, etc.) but I LOVE that it means I am going somewhere!
I don't really have any scary experiences but when we flew home from Disney World on Christmas Eve 2007 and I was SO SICK. I could barely walk! I seriously felt like I was going to die (OK, so I wasn't actually going to- but I felt like it). I didn't know how I was going to do it. We even had to take a taxi last minute so that I wouldn't have to wait in the airport any longer than we had to. We were the last to board. Luckily the plane was very empty and the flight attendant was very nice and catering to me. It was the first (and hopefully last) time I had to use those little bags that they provide....
I've had a few experiences were we had to sit on the tarmac for a few hours- that's no fun!
