WorldMate is a great app for air travellers. Download the app for iOS, Blackberry or Android and create a simple login and password for yourself.
Most ticketing is nowadays done online. So, when you get your e-ticket by email, just forward that email to firstname.lastname@example.org. You will instantly get a confirmation by email and within minutes, your itinerary will be magically organized in your App. It will carry your flight details, dates, and all other relevant information. If you go for the paid version, it will update your GMail Calendar and also give you flight alerts by SMS.
If you have hired a car or booked a Hotel, that will also show up. If not, the app will send you some attractive offers for the same from your destination location.
It works like magic. A must have app for the global traveller.
