flightsbr v1.2.0

CRAN release: 2026-08-21

• Minor changes:

  • When the package tries to download multiples but fails with a few ones, the package now only try to download again the files that failed in the first attempt.
  • The function read_aircrafts() now throws an error, as it has been deprecated in favor of read_aircraft() simply to fix a typo in the function name. The behavior and outputs are identical.
  • read_airfares() and read_flights() now cache the list of dates/files available from ANAC to a session-scoped temp file, governed by the existing cache parameter. This avoids re-scraping ANAC’s website on every single call within the same R session.
  • Files are now downloaded using httr2::req_perform_parallel(), replacing curl::multi_download().

• Bug fixes:

  • Fixed error in reading data from ANAC website. Fixed #52 and #51.
  • Fixed the select parameter in read_airfares(), which was silently ignored and had no effect on the columns returned. It now behaves the same way as select in read_flights().
  • Fixed get_airfares_dates_available() (used internally by read_airfares()) to retry requests to ANAC that fail transiently (timeouts, connection errors, HTTP 429/503) instead of silently dropping the affected year and returning an incomplete list of available dates.
  • Fixed get_airfares_dates_available() and latest_airfares_date() to fail cleanly with NULL when ANAC can’t be reached, instead of occasionally producing a nonsensical “data available between Inf and -Inf” error, or -Inf as a date.
  • Replaced a brittle hardcoded filename-length check (nchar == 55) used to filter valid international airfare files listed by ANAC with an explicit filename-pattern check, and added the equivalent check to the domestic airfare listing (which previously had no filter at all). This guards against malformed, duplicate, or misplaced files that ANAC occasionally publishes (e.g. typo’d names, files uploaded to the wrong year, re-uploads with (1) appended) corrupting the list of available dates.

flightsbr v1.1.1

CRAN release: 2025-07-24

• The previous version of {flightsbr} was temporarily taken down from CRAN because one of its dependencies (the {parzer} package) was removed from CRAN on July 1st 2025. This update of flightsbr v1.1.1 is simply intended to put the package back on CRAN.

flightsbr v1.1.0

CRAN release: 2025-05-19

• Major changes:
  • The default of all read_ functions now is to download data from the latest date available.
  • The function read_aircrafts() is now deprecated in favor of read_aircraft() simply to fix a typo in the function name. The behavior and outputs are identical. Closes #45
• CRAN policy:
  • updaed DESCRIPTION file removing ‘NeedsCompilation’

CRAN release: 2024-10-22

• Breaking changes:
  • The names of all columns in the data outputs are now cleanned with {janitor}
  • Function read_airports() now downloads v2 version of public airports data. Closes #41
• Major changes:
  • Function read_airfares() is working again. Closes #30. The prices of air tickets are now returned as numeric.
  • Function read_flights() with fixed decimal values in numeric columns. Closes #43
  • Function read_airports() with fixed numeric values for "altitude" column. Closes #42
• Minor changes:
  • Internally check of the consistency of date inputs. The date input must be consistent in either a 6-digit format yyyymm OR a 4-digit format yyyy.
  • New support function latest_airfares_date()
  • Fix error that stopped reading aircraft data read_aircraft() for multiple months when the number of collums differed across months. Fixed using data.table::rbindlist(fill = TRUE)

flightsbr v0.5.0

CRAN release: 2024-09-18

• Major changes:
  • Fixed ANAC’s broken link of public airports
  • Functions read_flights(), read_airport_movements(), and read_aircraft() now accept vectors of dates like c(202201, 202301) or c(2022, 2024)
  • Functions read_airports() and read_aircraft() now has a cache parameter.
  • The package is now significantly faster because it is using curl::multi_download() to download files in parallel. This brings the advantage that the package now automatically detects whether the data file has been updated and should be downloaded again.
• Minor changes:
  • Removed dependency on the {httr} package
  • Streamlined functions to simplify package maintenance and improve performance
  • Using {fs} to manage file paths and {archive} to unzip files
  • Reorganization of internal functions to simplify package maintenance
