VA Reward Seat Alerts

[butcheredit]

Does anyone have experience with Change Detection websites and know of a good one to use with the Velocity site? I know Expert Flyer doesn't have VA inventory but it must be pretty simple to just log in to the Velocity site and use a Change Detection tool/site to ping it occasionally and look for any changes.

I just want to be alerted to when/if a J seat becomes available on a VA flight from LAX to SYD on a specific date.
