Nonstop routes draw as one arc; connecting routes draw as two dashed arcs bending through the layover airport. Each node names its own air-quality reading; a destination’s paired list row also carries the itinerary-wide reading when the two differ.LHRACCCMNBCNDXBHKGLISJFK

The Clear Air Index

Every February we publish a year of measured air quality for every destination we fly to — and for every airport we connect through. The good months and the bad ones, unedited. Read it before you choose a season, not after.

From the journal

We stopped asking where is cheapest and started asking where the air is worth arriving into.

Six years of measurements and one uncomfortable finding: the month you travel changes the air you breathe more than the place you travel to.
