Whatever, the price difference for this flight (residents vs non-residents) is only € 20 at the Aerolines Argentinas website.
I just wanted to know what's happens at the airport if I come up with a ticket bought trough online travel agency like Lastminute Rumbo eDreams etc. Sometimes they not show whether the price of the flight is only for residents or not.​​​​​
Is there a fine or just having to pay the difference in the tariff, or denied boarding.

Tnahks!!!
