Claim: Lambert Field

A claim is US$79 for twelve months and puts this entry under your control: your website, your services, your certificates, your fleet, and an operator-managed badge. Verification is manual — expect a reply within a few business days.

Correcting a fact is always free and never requires a claim: send the source to the desk and the entry is fixed and dated. What the claim buys is control of the page, not the right to be accurate.
