flightsbr v1.1.1

• 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

• 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’

flightsbr v1.0.0

• 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

• 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

flightsbr v0.4.1

• Minor changes:
  • The read_flights() function now uses fread(encoding = 'Latin-1') internally to avoid issues with encoding. Closed #35.
  • The function get_airport_movement_dates_available() does not throw warnings of NA values anymore.
  • The read_aircraft() function now used fread(skip = 1) internally to read column names correctly.

flightsbr v0.4.0

• Major changes:
  • The functions read_flights() and read_airport_movements() now have a new parameter cache, which indicates whether the function should read cached data downloaded previously. Defaults to TRUE. Closed #31.
  • The function read_aircraft() now has a date parameter, which allows one to download the data on aircraft registered at ANAC at particular years/months. Closed #33.
• Minor changes:
  • All functions now return numeric columns with numeric class. Closed #32.
• Bug fixes:
  • Fixed bug when unzipping files for read_flights() function in Unix systems. Closed #31.
  • Updated link to private airports data changed by ANAC. Closed #34.

flightsbr v0.3.0

• Major changes:
  • Function read_airfares() is temporarily unavailable. See issue #30
• Minor changes:
  • Function read_flights() now accepts a vector of dates. Closed #29.
• Bug fixes:
  • Fixed broken link for data dictionary for airport movement data
  • Fixed code to rbindlist air fares from multiple years. Closed #26.
  • Fixed code to read a few dates that were not caught in get_airfares_dates_available() because of “.CSV” in ANAC url. Closed #27.
  • Fixed code to use get_airport_movement_dates_available()

flightsbr v0.2.1

• Bug fixes:
  • Fixed bug in read_flights() due to changes in ANAC data links.
  • Fixed broken link in intro_flightsbr vignette

flightsbr v0.2.0

  • New function read_airfares() to read data on airfares of domestic and international flights Closed #22.
• Minor changes:
  • The data downloaded in read_flights() and read_airport_movements() are now cached in temp dir. Closed #20.
  • All columns are now returned with class character. This fixes a bug in the read_airport_movements() function. Closed #20.

  • Fixed bug that stopped flightsbr from downloading 2022 data.

flightsbr v0.1.1

• Bug fixes:
  • functions read_flights() and read_airport_movements() no longer have side effects on objects named month and year on the global environment. The split_date() support function was removed from the package. Closed #17.

  • Using a simpler / slightly faster version of latlon_to_numeric() with suppressed warnings.
  • Update package citation, adding OSF preprint DOI.

flightsbr v0.1.0

• Minor changes:
