The head of Brazil's airports authority, Infraero, said the Gol plane collided with another smaller plane in the Amazon region, the Globo news agency reported.
The smaller plane, an executive jet, was able to land even though it suffered wing damage, Globo reported.
Gol flight 1907 left Manaus in the afternoon but did not arrive in Brasilia as scheduled, a spokesman for the Manaus airport said.
The company said the flight had 155 passengers on board but made no mention of crew members.
Brazil's civil aviation authority said the plane was transporting 155 people.
