Glitches on this App

I paid for the professional version of this app and expected to get great information because of the way it is set up. However when I tried using it todayit was unable to find united airlines flight 417 from LAX to OGG-- said "flight not available" so I had to go to a different app and purchase it in order to get my friends flight confirmed. This is not a reliable way to acquire travel flight info
