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.
