Source-derived summary

Viação Aérea Arco-Íris S.A. was a Brazilian airline founded in 1945. Flight operations ceased in 1948.

History

Arco-Íris was founded in March 1945 and the first flight was operated on July 12, 1946 between São Paulo-Congonhas and cities within the states of São Paulo and Paraná, being the first carrier to serve Londrina.

Due to financial problems the airline ceased operations in 1948. It was later sold to a group of entrepreneurs from Rio Grande do Sul, who moved its head-office to Caxias do Sul, right on the main operational area of Varig. For this reason, the new owners had extreme difficulty in establishing operations. Finally in 1950 Arco-Íris had its operational authorization cancelled.

Assis – Assis Airport

Editorial analysis

Why this record matters

“Viação Aérea Arco-Íris” is worth following because a concise public description often conceals a longer documentary argument. Here, Viação, Aérea and Arco-Íris provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 21, 2026. The linked authority identifier is Q7924548. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1945, 1948, 1946 and 1950.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
