You don't have to be CEO to travel like one, say Expedia Corporate Travel's VIP agents. In fact, some executive-style perks can be yours for the mere asking.

"Ask, ask, ask -- and do it nicely," says Holly Davis, VIP agent for Expedia Corporate Travel, the world's No. 1 on-demand, full-service corporate travel agency. "The people behind the counter at the airline, the hotel, and the rental car agency hold your travel fate in their hands. Treating them nicely and asking politely are sometimes all it takes to get a better seat or bigger room."

Executives often get preferential treatment because they're willing to pay for it and because they rely on the expert counsel of Expedia Corporate Travel pros like Davis, who know how to get first-class perks that not every traveler knows about.

"There are lots of little things that we do to make executives' travel plans go smoothly," she says. "We have contacts that allow us in certain situations to ask for upgrades and confirm late arrivals at the hotel. We know that the first flight of the day is most likely to be on time and we're able to explore different modes of transportation so the executive gets where he or she needs to be most efficiently and comfortably."

These tips from Expedia Corporate Travel may help you travel like a VIP:

- Collect air miles through just one or two frequent flyer programs. Racking up a few thousand miles through a dozen different airline programs won't get you anywhere. Instead, determine which airlines you fly most often and who their air, hotel, and travel partners are. By consolidating your mileage, you may work your way more quickly to free tickets, better seat assignments, and class upgrades. Airlines often offer express check-in to elite-level mileage members and you will gain leverage when dealing with the airline's customer service department if you ever run into a problem.

- If you usually fly from the same airport on the same airline, take the time to recognize personnel. Ditto with hotel employees. Check-in staff often hold the power to decide who gets upgrades and who doesn't.

- Look the part. If a seat opens up in first class, you may be more likely to get bumped up if you're not wearing thread-bare jeans and old tennis shoes.

- Paying out of your own pocket for an upgrade to first-class may be money well spent. If your company pays for a coach fare, find out how much more a first-class ticket would be. Sometimes the price of an upgrade is as little as $40 or $50.

- Know that taking a limousine may be cheaper than a cab - especially when you factor in the time you'd spend waiting in the taxi line at the airport.

- Consider using a car service if you've got appointments at multiple locations within a metropolitan area; it may be less expensive than a cab or a rental car and you won't have to worry about directions or parking.

- Check with clubs and associations to which you belong to see if they have any programs through which you can get perks like special seating, hotel upgrades, or access to VIP lounges.

- Don't assume corporate travel agencies only serve Fortune 500 companies. Even the tiniest of companies can benefit from the expertise and experience of professional agents.
