How to read the monthly fare data
- Compare one-way prices only with the one-way series and roundtrip prices only with the roundtrip series.
- Use the fare count to judge how much current evidence sits behind a monthly average.
- Treat the lowest fare as an observed option, not a guaranteed future price.
- Open a month to compare exact departure dates, airlines, stops and travel time.
