The first option on the main menu of the app is the most useful option, the option to get information about your trips including your current trip. There is a direct link to get your boarding pass. A few months ago, I described how you can use your iPhone as a boarding pass by having an airline send you an e-mail with a link to a webpage containing an electronic boarding pass. It is every more handy to use the Fly Delta app because you don’t have to find that old e-mail containing your boarding pass. Note that electronic boarding passes cannot be used at every airport yet. For a list of the 60+ airports that currently support Delta mobile boarding passes, look on this page. It includes all of the Delta hubs and lots of other airports. It is nice to not have to worry about a paper boarding pass, especially when you are away from home and don’t have easy access to a printer. You can just launch the app when you are standing in the TSA security line and access your boarding pass in a few seconds, and then do the same thing when it is time to board the plane.
