I find myself using this more and more everyday especially since I am waiting for upgrades to clear every week this month. There are still many improvements to be made but overall I am quite happy that this app is now out.
One issue I do see if the Flight Status button on an itinerary does not give as many options as it you were to search Flight Status from the home screen (for example seats and upgrade lists.)
Another issue is the Push Notification. 2 weeks ago i did not get any notification about a MX delay and have yet to receive a "your upgrade has cleared message." Have any of you had much luck with Notifications?
Now they need to think outside of the box and add maps, dashboards and other information that would make this much more interesting.
