The official text is ambiguous and likely contains a translation error: 'Skyhigh Aviation Services is limited to transporting brachiocephalic (flat-nosed) breeds' (EN) / 'Sky High Aviation Services se limita a transportar las razas braquiocefálicas (nariz chata)' (ES), followed by an explanation that such breeds have narrow airways and breathing difficulties. Literally the sentence reads as 'is restricted to transporting brachycephalic breeds' (i.e. carries ONLY them), which contradicts the rest of the page (about dogs/cats in general) and the logic of a health-risk warning, which normally accompanies a BAN rather than a permission. The most likely intended meaning is 'restricts/does not accept brachycephalic breeds' (a typo or mistranslation of the Spanish 'se limita a NO transportar' or 'restringe el transporte de'). Set to true as the safer reading (better not to promise carriage for a pug that would actually be denied boarding), but human verification is strongly recommended — verify_recommended=true, the exact quote is given in source.quote.
