Although Brazilian airlines Azul and GOL are fierce competitors, both believe there are vast opportunities for urban mobility in Brazil and are each working to create a new mode of transport in the country.

Delta Air Lines is drawing criticism from one of its own shareholders for the role it is playing in Aeromexico’s Chapter 11 restructuring.

Citing internal restructuring, Sao Paulo-based start-up carrier Itapemirim (ITA Transportes Aéreos) has halted operations, and the Brazilian civil aviation authority subsequently suspended the airline’s air operator’s certificate.
