When it comes to booking last-minute business trips, sites such as Orbitz.com, Expedia.com, and CheapTickets.com are great for tracking
What's more, Travelocity recently launched Travelocity Business, a full-service corporate travel agency that negotiates exclusive airfare rates, travel reports, and one-stop flight, car rental, and hotel packages.
Finally, don't forget to bookmark individual airlines as well, especially if you have frequent flier memberships set up. If last-minute travel is something you're going to have to get used to, it's a good idea to have a bag always packed and at the ready so you don't forget important items in your mad dash to the airport.
