Maybe. Be prepared, know where you are going and this:

Do you speak Castilian / Spanish? Be politely assertive if things are getting tight and let the official folks know you are on a tight deadline, say a lot of "disculpe" (deess-COOL-pay" and edge into the front of the queues holding up your connecting BP, etc.

Key phrases

"Mi avión esta listo para salir" (my airplane is ready to leave) - "me ah-vee-OHN ess-TUH LEES-toe PAH-rah sol-EER"

"Con permiso" (please give me permission / forgive me) - "cone pear-ME-soh"

and of course, "disculpe" as above

Just these words with politeness but obvious intent and worry will cut you a ton of slack. Latinos can ignore queues and be pushy, but dissolve at some Latin politeness.
