Want to save cash on airfares? Well, you better start your diet now. Bloomberg News reports that sometime soon the cost of your flights will depend on your weight.

Although this is bad news for yours truly, I guess this makes sense, right? The more you weigh, the more fuel is needed to get to your destination.

Robert Mann, head of R.W. Mann & Co., an aviation consultant based in Port Washington, NY, sums it up best:

"If you look at the air-freight business, that's the way they've alwaysdone it," he said. "We're getting treated like air freight when wetravel by airlines, anyway."

Here's some more travel news you can use:

*  American Airlines has announced that as part of its cost-cutting it will end its "Nerd Bird" flights from Austin to San Jose as of August 25th.  AA has been flying this route for the past 17 years, servicing many tech workers from both cities – hence the nickname "Nerd Bird".

*  The New York Times reports that the airline on-time statistics that the government furnishes account for only two-thirds of the flights that take off or land in the United States.  The latest government statistics show that the airlines had a 79% on-time record in April, an improvement over the typical 75% rate.  However, that gain now seems more of an estimate than an accurate measure of the industry's overall performance.

*  The Georgia Supreme Court ruled against Expedia in a lawsuit over hotel sales tax collections that could have repercussions for other online travel companies and for hoteliers around the country.  Expedia had been chargingcustomers a higher “room rate” than it pays to hotels, but hotels remitoccupancy taxes based on the wholesale rate of the room. Expedia – and other onlinetravel providers – had been pocketing the difference.  If other states follow Georgia’s lead, consumers will face the realitythat rates on online travel sites may reflect the increased taxes.
