Nice sale with Azul from Lisboa, Portugal to Rio de Janeiro and Sao Paulo, Brazil during the peak Christmas travel time. This assumes that Covid-19 allows travel between Europe and Brazil , that Azul remains operating and that travel is somewhat closer to normalcy.
Flights are via their hub in Viracopos VCP and the intra-Brazil segment is in Economy class. Long haul segments book into I class with intra-Brazil in Y class.
I credits at COPA Airlines ConnectMiles (CM) at 125% , TAP Portugal Miles & Go (TP) 200% and United MileagePlus (UA) 150%.
