A treasure trove of business travel tips

While I frequently visit CNN.com for the latest news headlines, I rarely check that site for travel information. However, they just published a great feature chock-full of travel tips from business travelers, so I highly recommend checking it out.

Here's a peek at what you'll find:

> A report on the new Diamond Lanes program, an "express lane" for those airport security checkpoints.

> "Confessions of an Airline Agent," an enlightening look behind the airline counter.

> Tips on tipping internationally: if you're in a restaurant in Fiji, Malaysia or South Korea, should you leave a tip?

> Four scams from rental car companies, including the apparently widespread gas gauge scam.

And much more... including the common sense business traveler tip I never would have thought of: When you arrive starving at your destination because your airline didn't serve a meal on that cross-country flight, call ahead to your hotel and place a room service order to be waiting in your room for you.
