Each metric is compared against the airport's peer cohort — airports in the same size band by FAA CATS actual enplanements for the fiscal year shown. The shaded bar is the cohort's interquartile range (P25→P75, i.e. the middle half of peers); the vertical line is the peer median; the dot is this airport. Green = better than the median, amber = worse.
Direction: for Cost per Enplanement and Debt per Enplanement, lower is better; for Days Cash on Hand and Operating Margin, higher is better. The quartile label reads position in that direction — Top quartile is best-in-cohort, Bottom quartile is the weakest.
This peer cohort is computed independently of the display hub class used elsewhere (which is based on BTS T-100 traffic), so the two can differ for the same airport. Source: airport_financial_scored (phase-4 deterministic scoring).
