Here's a very cool app that I wish more airlines get in on. The new Detla app for BlackBerry is great if you're a frequent Delta traveler and has some great features to help out in your travels. Everyone knows traveling on any airline can be a huge pain. From checking in to getting through security and all that entails, its just a long process that most wish we didn't have to endure. With the Delta app, you can now checkin for flights, download mobile boarding passes, get push alerts for flight and gate changes, search your SkyMiles balance and even save a photo and note of your parking spot -- all through your BlackBerry. Overall a very feature-rich app for the frequent traveler. It's totally free and available for most devices from BlackBerry App World via the link below.
