If you want to change your seat or make a reservation, you can do so in four different ways: the first is on the official GOL Argentinas website; the second is by calling the company's sales center; the third is through the self-service kiosk at the airport; and the last is at the GOL Argentinas service desk during check-in.

To change your flight or boarding date, you must do so on the official GOL Argentinas website. Then, access the "Your Flight" option in the navigation bar and change it there. Remember that fees or penalties may apply for changes depending on the fare you choose. You can also change your flight by calling the call center directly. 

You will see an increase of $40.00 or 10% in the fare value if you purchase your ticket at the reservation center or at GOL stores and kiosks. 10% will be charged if the purchase exceeds $300.00.
