Reviews and reputation counts for 45 of the 100, what the company states on its own website for 30, and its website and record for 25. Nothing in this panel has been checked by anyone here: the middle pillar is the company writing about itself and a crawler reading the sentence. How the score is built.
What this site read
Statements on Diamond Air’s own website
- Says about 10 years in the trade
- Says it holds a trade licence
- Says it is insured
Each line above is a sentence a crawler found on that company’s website when the site was read on 2026-08-30. Nobody here rang a regulator or looked at a certificate, which is why every line begins “Says it”.
