4. Take your cell phone. Use those extra or unlimited minutes, especially if you are traveling within your local calling region or have a nationwide service contract.
5. Walk instead of taking a cab. This works great if you are staying in a city center where everything is close by. It also will help you work off those restaurant and expense account meals.
6. Check if your company has negotiated discounted rates with airlines, hotels and car rental agencies.
7. If you are renting a car, get directions to the gas station nearest the rental agency. This will make you more likely to use it when you return, so you avoid paying rental agencies' high gasoline prices.
8. Know the cancellation policies on your airline tickets, hotel and car rentals. Many of the lowest rates are nonrefundable or require change fees. But policies often are revised. Many airlines will let you apply the cost of an unused ticket to the purchase of a new ticket within a year, as long as you canceled your reservation before departure.
