Last year when we did our trip, we would have been flying on Trip Airlines if we hadn’t chosen to take the bus to certain eco-tourism hotspots such as Alta Floresta and Itaituba. Now, Trip has merged with Azul Airlines. It’s become much easier to book on them as they now have a foreigner’s booking mode. The old Trip Airlines didn’t accept non-Brazilian credit cards. Click on the US flag for an English version. I have highlighed in yellow some airports that would be of interest to eco-tourists. Sorry no frequent flyer program but at least the fares aren’t expensive!
