Real (CPI adjusted) Domestic Discount Airfares

Real (CPI adjusted) domestic discount airfares collected by the Bureau of Infrastructure and Transport Research Economics (BITRE). The dataset contains the cheapest available return fares based on a departure date of the last Thursday of each month with a return two weeks later. Data is sourced from airline websites three weeks prior to the departure date and was last updated on April 20, 2026.

Use Cases

• Modeling inflation's impact on transport costs based on CPI-adjusted fare data
• Analyzing seasonal trends in domestic airfare pricing based on monthly sampling
• Benchmarking airline discount pricing strategies based on collected fare data
• Forecasting consumer travel costs based on historical, inflation-adjusted price series

Strengths

• Data is explicitly adjusted for inflation using the Consumer Price Index (CPI)
• Fares are collected via a consistent methodology from airline websites
• Sampling uses a fixed schedule (last Thursday of the month, return in two weeks)
• Dataset is provided by the authoritative Bureau of Infrastructure and Transport Research Economics (BITRE)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect temporal bias inherent to the specific monthly sampling method
