ON CALL
Delta, Continental, and Northwest recently tested cell phone check-in at some airports, and Qantas will introduce the service early next year. Enter your phone number at check-in and a bar code arrives on your phone by e-mail or text message. At the security checkpoint and the gate, agents scan your phone's screen just like they would a paper boarding pass.

GET WITH THE PROGRAM
Forward your confirmation e-mails—from airlines, hotels, and even Priceline—to plans@tripit.com, then TripIt.com extracts the relevant information and creates an online itinerary. If your phone has a browser, you can point it to m.tripit.com for a simplified version of the site. If not, just e-mail plans@tripit.com and you'll receive your travel plans right away.

RAVE REVIEWS
GoPlanIt.com also builds itineraries, but this site organizes trips based on your preferences (romance, nature) and suggests activities, hotels, and restaurants according to how highly they're rated by travelers on other sites, including Yelp and TripAdvisor. So far the site customizes itineraries for ten U.S. cities, but users post their own personal itineraries for dozens of others.
