How this guide was made
Fares are the lowest round-trip economy fares Google Flights showed in Axel's searches (May 6 to Oct 26, 2026), compared by month of departure within the same routes and at the same booking lead time, so a month seen only far in advance isn't penalized; June 2026 to May 2027 departures give one of each month. Crowds are TSA checkpoint counts; delays are the Bureau of Transportation Statistics' on-time data for Sep 2024 to Aug 2026, both Januaries (and so on) pooled.
