Until earlier this year, I hadn't flown since before 9/11. I was prepared for the worst when I walked up to Security. It actually turned out to be easier than pre-9/11. I didn't get the nudoscope and didn't have to boot my laptop (a huge time waster). I did have to slip off my shoes at Dulles, but not at Heathrow. Nobody wanded me at either location, I just walked through the metal detector and retrieved my stuff.
When we planned our vacation to Disney this summer, our initial plan was to drive the 14hrs from here to there. However, when I saw gas prices rising and predictions of $4-$5 gas for this summer, I ran the numbers and took a look at discount airline tickets. I found I was able to fly my entire family for $800 while a drive would cost a minimum of $300 (not including meal stops and with gas at its current price). The idea of a 2hr flight vs a 14hr drive with two young children is appealing in the extreme (I've made longer drives 3x before, so I know how it works). Not to mention the wear and tear on our vehicle...
