How do I cancel an alert sent to my mobile phone? I get an update on that flight number each day.

Head on back to the “My Alerts” area of your profile and change the alert from active to non-active (or whatever the opposite is on that page).

Edit to do step by step:

Click on “My FlightAware” (top right of the screen)

Click on “Manage Flight Alerts” under the “Customize” link

Under “Active Alerts”, click on the “Edit” button next to the flight you are referring to

Change “Enabled” from YES to NO

Click on either “Submit” or, you can just simply delete it by clicking on the “Delete this alert” button.

Thanks a bunch.
