Full body scanners are marching into U.S. airports as the Transportation Security Administration (TSA) announces new pat-down procedures. Many airline passengers in the U.S. face an uncomfortable choice. Do they use the very revealing (but supposedly anonymous) body scanner, or do they subject themselves to a rather personal physical search?

American Airlines first separated the first few rows in the economy section to give its high-tiered frequent flyers an opportunity to sit close enough to first class to sniff the wine cork. Now others will have the opportunity to sit as far forward as the first three rows in coach ... for a fee.

JFK International Airport in New York is testing a system that allows airlines to ask for their preferred takeoff times and then schedules them in 15-minute blocks. In an airport notorious for some of the country's worst delays, has the system helped?

Things that go bump in the flight can be among the most unnerving experiences as airline passengers. Some of us who fly frequently grow accustomed to bumpy flights and take the unsettling movements in stride.

No matter what your level of flight expertise is, it's always a good time to pay attention to what you're doing in flight.

Some airlines are installing lie-flat seats for their premium customers. So what would a completely opposite approach look like? Ryanair has the answer. We don't think you'll be able to sit down for this one.

The airlines issued grave warnings about "unintended consequences" when the 3-hour tarmac delay limit went into effect recently in the U.S. Since then, there have been some cancellations but there have also been fewer stories of passengers being trapped in airplanes for hours on end. Still, summer weather will test the readiness of airlines and airports and will challenge the limits of this rule, as a recent incident demonstrates.

If flying gives you a headache, imagine the feeling of hitting your head on the seat in front of you at 16 times the force of gravity. That is what new airline seats are required to withstand today in order to keep you relatively in place and to prevent such unfortunate body-to-seat confrontations. But what if you're flying on an older aircraft?
