Asuncion is a small and simple airport. From airport gate to curbside the distance is no more than 50 meters. Upon arrival on AA (this was last month before AA cancelled their service to ASU) immigration was quick and efficient but baggage claim seemed to take forever. I must’ve waited for over 40 minutes which was unusual. Baggage claim in ASU is slow but not that slow. Be prepared when arriving into Asuncion’s baggage claim area to be swarmed by baggage porters looking to make a big tip. As soon as you tell one “no” another one will approach you. Departure wise the departure hall is not that big and can easily get crowded. Especially between the hours of 1600-1800 when flights to Buenos Aires and a couple of flights to Sao Paulo are departing around that time block. It seems in Asuncion when one person is going out of the country at least six relatives show up to say goodbye. Thus the departure hall can easily turn into a sea of people. There are two small restaurants on each side of the departure hall but these were full of departing passengers and their large number of relatives/friends. Check-in quick and efficient. AA had Asuncion’s departure tax already included in the ticket price so I skipped the departure tax window. I’m not sure if Varig does the same and Dale’s review answers the question on TAM. No line for immigration and it’s off to wait in the departure gate area. A restaurant is inside that allows for a bite to eat or a final opportunity to sample Paraguay’s local beers. I always chose the latter. A number of street-style shops selling Paraguayan leather and lace products are located in the middle of the gate area. Between them and the duty free shop in the corner of the waiting area I really couldn’t find anything worth buying. Business class passengers on AA did not have a business class lounge to wait in and I saw no indication of one for Varig’s business class passengers either. TAM flights into Asuncion are all Y configured. ASU has made some improvements over the years such as the addition of the duty free shop. Overall Asuncion’s airport is a basic and “gets the job done” type of airport.
