R$4–6 gets you straight from POA to Centro on one bus
Linha de Ônibus Aeroporto Centro runs as a standard city bus linking Porto Alegre-Salgado Filho (Terminais 1 e 2) to the Centro Histórico for about R$4–6, using the regular urban fare. Off-peak, riders report 25–30 minutes to hotels near Mercado Público; in peak traffic along Avenida Sertório and Farrapos, plan for 45–60 minutes instead.
Buses run roughly every 20–30 minutes during weekday daytime, then thin out at night and on Sundays, so missing one around 22:00 can mean a longer wait. Some trips pull into the internal airport loop by Terminal 1, others stop only on the main avenue outside the entrance, which adds a short walk with luggage of around 200–300 meters.
This is a one-seat ride straight into downtown streets like Farrapos and the Rodoviária area, which locals call “meio lento mas direto” compared with the Aeromóvel + Trensurb combo. Regulars often ride only as far as Mercado or Rodoviária stations, then hop to Trensurb or an app car and skip the slowest central stretch that can add 15–20 minutes in rush hour.
Expect a normal city bus interior, not an airport coach: there is no dedicated luggage rack, and r/portoalegre users complain about standing with suitcases when the vehicle fills with airport staff and commuters. Seats go fast on weekday mornings around 07:00–09:00 and late afternoon around 17:00–19:00, when bunching also happens and you may see two buses in 5 minutes, then nothing for 30.
How to use Linha Aeroporto Centro step by step
- 1. Exit your terminal: From Terminal 1 arrivals, follow signs toward the public bus stop; from Terminal 2, allow 5–10 minutes to walk or use the shuttle to T1.
- 2. Decide your stop: For the first bus, check if it enters the terminal loop or only passes on Avenida Severo Dullius outside; the avenue stop usually sees the bus a few minutes earlier.
- 3. Confirm the destination: Look for “Aeroporto–Centro” on the front signboard, and ask the driver “Vai até o Centro?” if you’re unsure.
- 4. Pay on board: Enter at the front door, pay the standard Porto Alegre fare (around R$4–6) in cash or card if accepted, then pass the turnstile.
- 5. Stow your bags smartly: Keep suitcases near you without blocking the central aisle; aim for a side seat so you’re not in the door space when people board at busy stops.
- 6. Pick your exit point: For hotels in Centro Histórico, get off near Mercado or Rodoviária; if your stay is farther out, use those same stops to transfer to Trensurb or an app car.
- 7. Watch your timing: After 21:00 and on Sundays, pad your plans by at least 20–30 minutes because headways stretch and real-world travel can hit the 60-minute mark.
One practical tip: if you land between 07:30–09:00 or 17:00–19:00, aim for the first Aeroporto–Centro bus you see on the main avenue stop, even if it means a short walk, to beat crowds and grab a seat before the city commuters pile on.
