How this guide was made

Fares are the lowest round-trip economy fares Google Flights showed in Axel's flight searches from May 6 to Oct 26, 2026, compared within the same routes so that a route's general price level doesn't count as a holiday effect. The cheapest-day figures compare departures on each day with the same routes' departures 15 to 28 days either side, at the same booking lead time; days with too few fares are left out. Crowd figures are TSA's daily checkpoint counts, 2019 and 2022 onward; delay figures are the Bureau of Transportation Statistics' on-time data. The booking window combines Axel's fares with the published studies cited, each of which measures something different (see the table).
