Remove old iPhone

My FlightAware account thinks I have two iOS devices instead of one. I’m sure it’s my old iPhone. How can I remove this old iPhone?

Thanks!

I have gone ahead and removed it! Thanks for letting us know.

Hi, I have same problem. Well, not sure if it actually a problem. When I create a flight alert, I see 6 iPhones. The only one I am still using is the iPhoneX. Thanks.

I have removed all the old iPhone that were associated with your account. You should now only see your IPhoneX.
