I downloaded the app. It has a major limitation for me. Unless I am missing something you can't set a date range to check for trips. I don't want to get messages for trips all month long. As a example I have a window where I want to pick something up in Jan. Its a 6 day block. I would want the app only to alert me on flights in that date range but I can't find a way to do it. Am I missing something?
