Well, think about the many, many flights that have been flown since 9-11. How many have been hijacked? None, that I know of. That's how I would see it. Still, I will pray too.
Some random, "flighty" thoughts:
I know you've been on a flight before, but I'll just say my little "story" (it's no big deal and actually has little to do with terrorism) for those who haven't flown:
I remember the first time I went on a plane back in summer of 1999. It was from BWI to Dallas/Fort Worth (my parents & I were heading to San Diego for a vacation--we haven't taken one since--probably because we just bought a new car last year). At the beginning I just remember panicking and trying to distract myself with the little video of them showing how to put the oxygen masks on and putting your head between your legs...geesh. I guess it's necessary. I remember when we first took off and I heard something and felt something like vibrations under my feet, I said loudly, "What the **** was that?? [censorship mine!]" Yeah, I actually was a Christian at the time :o . My panic was contagious because the guy in front of me, well, his eyes suddenly got big! Don't think it was because I cussed. But then it occurred to me almost immediately afterward I said that that it was just the wheels going back up into the plane. My dad believes that the area right around the wings and the wheelwell is the safest area of the plane. I dunno. It just took some time to get used to it. Fortunately, there was very little turbulence during the flight, but you can bet that I paid attention to it every time! After we arrived at Fort Worth, I seriously considered saying to the pilot, "Thank you for not killing us all!!!" But I didn't. Didn't want to create a self-fulfilling prophesy or anything.
After about an hour of waiting at the airport (actually it was more because some other peoples' flight(s) was late), we headed on towards San Diego on another flight. I remember the little bistro bags and the lame little lunches inside for both flights. What, no shrimp? We collected some airline peanuts; the reason they give those out is because they have a lot of protein and they help hold you over pretty well for the next meal. Then we had to give the bistro bags back. I remember that the stress made me feel a bit nauseated. I was sweating a bit, because it was hot and I was stressed. And I hadn't slept well at all the night before. I also remember thinking that you had to pay mucho deniro just to be comfortable like the people in first class. Felt like sardines in a can; I hated it! I think we were on a 757.
It just takes time to feel comfortable. I know a hijacking can happen at any time during the flight, but just trust God. Trust me, I did pray a lot, before and during. After, it was a lot of thanksgiving prayer! Let the statistics speak. Statistics can be exaggerated, but...anyway...you'll be fine, I think.
By the way, has anyone noticed that I've been a bit long-winded lately?

I just have a lot of thoughts. Perhaps I'm experiencing a bit of mild mania

. What can I say.
