Until the airlines are able to guarantee the bags are going to be at baggage claim within a certain period of time, the tendency is going to be to carry on.

LaGuardia is one of the few airports in the country that is controlled by slots so there are only a certain amount of airlines that are allowed to take off and land.

Last summer as you recall the planes were bulging at the seams full of passengers, so there's a lot of equipment on those routes now that the airlines are trying to keep full this winter.

You can get a ticket on United and only be able to carry on a very small bag. And then... the following week you'll get on Continental airlines and you can carry on just about anything you want, it fits.

There's ... a liability issue. If an American Airlines plane hits clear air turbulence and someone is injured, they can fall back on the fact that they have it stated in their policy that they must be seated with their seat belt fastened at all times.

The airlines simply have a lot more money right now... They're taking some of those profits and plowing them back into an improved product.
