For a deeper dive into carrier-specific policies and owner-verified experiences, the complete 2026 airlines that allow cats in cabin guide is an excellent companion resource to this article.

Pre-Flight Preparation: Stress Management and Veterinary Health Checks for Cats

Before booking any flight, a veterinary health check is non-negotiable. Most airlines require a health certificate issued within 10 days of travel, and your vet can flag any conditions that make flying risky for your specific cat.

Stress management is equally important. Bonqat (Orion Animal Health) is currently the only pregabalin product licensed for cats, approved in the EU, UK, Norway, and Iceland specifically for alleviating acute anxiety associated with transportation and veterinary visits. Ask your vet whether it’s appropriate for your cat’s travel needs.

Carrier acclimation should begin weeks before departure. Leave the carrier open at home with familiar bedding inside so your cat associates it with safety rather than stress.
