This method is a bit of a hot mess.

0. `_get`
1. client details like `verify_ssl` are unrelated to getting scheduled flights, so I'd expect them to be dealt with elsewhere.
2. You parse JSON twice, and then extract values. Again, that parsing should probably happen elsewhere.
3. It's unclear that `add_utc_time` returns the flight array that you'll be giving back to the user. That name is very confusing.
