What "best" means here, and what it does not

Punctuality is one dimension of a good airline and not the one most people would name first. It is, however, the only one that is measured the same way for every carrier and published by somebody with no stake in the answer — which makes it the one worth ranking on.

It is also route-specific. An airline near the bottom of this table may be excellent elsewhere; what the table says is how it ran on these particular routes over this particular period. The same list, worst first →
