Pick an airline. Aerolíneas Argentinas flies 3-4 times daily from both airports. Sky Airline operates 1-2 daily flights from Newbery. Both airlines use similar aircraft (Embraer regional jets) and flight times are identical at 1 hour.
Book your ticket. Book directly on airline websites for best customer service, or use Skyscanner/Google Flights to compare prices. Tickets cost $120-180 USD in economy. Book 2-4 weeks ahead for best prices. Avoid booking during Uruguayan summer (December-February) when prices spike.

Arrive at the airport. Get to the airport 2 hours before departure for international flights. Check-in online 24 hours prior to avoid lines. Security is straightforward - remove electronics and liquids as usual. Immigration takes 5-10 minutes with proper documents.
