We are going on the Caribbean/Amazon trip on March 3, 2024. Our flights are free. Flight back from Manaus goes from MAO to São Paulo (which is 4 hours south of Manaus) and then 10 hours to NYC and onward to Toronto. Seems to be the only flight available. When I look on MVJ the alternative, which is basically the same, is an additional $850. Asked about upgrading and apparently this can’t be done until ticketing and then at that point if you can’t upgrade it is too late. Anyone have a decent flight itinerary for this route. Wondering if perhaps the “free” means no choice. Agent told me to call back in a few weeks to see if anything else comes available. Doesn’t sound too promising.
