Check out INM Guadalajara or Mx city

Can you still check out with INM when flying from Guadalajara to Mx city and then leaving Mx.   At one time we could do this saving going to INM In Mx city. 

Depends on the INM agent at the desk. Sometimes yes, sometimes no.

If check out in Guadalajara wonder if Mx city will honor it ?? A few years ago the Guadalajara reporter said Mx city was ok With checking out of Mx in Guadalajara. But that was a long time ago.

We never had an issue when it was OK'd in GDL.  It's just the airline that will see it.  

Just be sure if you are given the Stamp Out in GDL that you do NOT turn it into the airline at GDL (though they won't ask for it since it's a domestic flight).

You will have to show it at MEX boarding gate (they will keep half of it).
