I tested it. Been testing for a couple of months. I believe it is $10 one time. Here is the flyer:
SPOTFLIGHT
Delta Air Lines Open Time Table application for pilots.
The highly anticipated SpotFlight app is the first of its kind available from the Google Play Market. Now Delta Air Lines pilots can parse the Open Time table automatically or manually and be notified immediately when there is a trip matching their preference. The notification is audio and similar to getting a notification of a text message. SpotFlight provides the ability to enter all the settings that the actual Open Time website offers as well as additional filters to ensure you are notified only of trips you want. Pilots are now able to target and search for specific trips without ever accessing their computer. It's as simple as inputting your username and password, then pressing the start button. This secure app runs efficiently in the background without distracting the user. Months of testing has shown battery and data usage is minimal and not noticeable to the average user.
This app is available through the google play store (search for spotflight in apps) or at spotflightapp.com. This app is $9.99 one time. Never pay anything again for this app! This offer is good through 2012 and then will go to a subscription service. Planned fee starting January 2013 is $2.50/month. If you get the app before 2013 you will get all updates and add-ons free forever! Sign up now, $9.99 once, never pay again and get all improvements, upgrades and updates free!
Check it out. It works great!
