If you on a multi destination journey it can be stressful trying to manage airline tickets, hotel reservation confirmation forms so why not let technology make it easier by using an app?
Free programs and apps like Tripit can make building your itinerary with related details (address, phone number, rate, confirmation number, flight details, dates, etc.) easy. You can let the app read your email or just forward emails to Tripit (or similar apps) once you have an account. The app will self-populate your itinerary. No need to hunt around for the details while you are on the go.
