How each airline actually performs.
10 US airlines, 1,464 validated statistics between them. Cancellations and delays, what they charge in fees, what they spend on lobbying, and how often they deny passengers boarding. Every figure cites the federal dataset it came from.

Which airlines are missing, and why
Regional carriers and defunct airlines are not covered, even where we hold data on them. That is a deliberate limit rather than an oversight, and the reason is worth stating.
Our statistics database holds 95 different spellings for roughly 30 airlines, because different federal datasets name carriers differently. Some are harmless variants of the same airline. Others are not: FL was AirTran, HP was America West, and YVis Mesa. Horizon Air is Alaska’s regional subsidiary and Envoy Air is American’s, but each is a separate carrier with its own performance.
Matching those by resemblance would risk attributing one airline’s record to another, which is the worst error a site like this could publish. So we map carriers by hand and leave 928 rows unmapped rather than guess. An airline also needs at least 4 validated statistics before it gets a page at all.
How to read these
A scorecard tells you what happened, not what you are owed. If something has gone wrong on a flight, the rule that applies is on the passenger rights pages. Airports are covered separately at /airports.
Our sourcing and statistical standards are on the editorial guidelines page. Corrections are logged at /corrections.
