Azul Linhas Aéreas Brasileiras (AD, Sao Paulo Viracopos) has firmed up a Letter of Intent (LOI) with Embraer (EMB, São José dos Campos) for twenty-one E195-E2s.

The tentative agreement was signed during this year's Farnborough Air Show and, combined with the Brazilian operator's previous order for thirty E195-E2s, takes its overall backlog for the type to fifty-one.

Azul is the E195-E2's launch operator and will take delivery of its first aircraft in 2019.

Collectively, the E2s will replace Azul's E1 fleet which currently stands at nine EMB-190s and fifty-four EMB-195s. Earlier this year, airline chairman David Neeleman said he anticipated completing the transition by the end of 2021.
