The Congonhas Airport in São Paulo is a busy domestic airport with efficient check-in, though it can get crowded during peak hours. The terminal has decent food options, shopping, and free Wi-Fi, but seating can be limited. The airport is convenient for quick city access, but Ryanair CGH Terminal does not operate there because it primarily serves European destinations. https://www.findallterminals.com/ryanair/ryanair-cgh-terminal-sao-paulo-congonhas-airport/
