Chief overthinker, serial airline-policy checker, and emotional support human to a 9-year-old Chihuahua with main character energy.
This project started after trying to plan an international relocation with a pet in cabin and discovering the internet is full of conflicting airline rules, vague destination guidance, outdated pet travel advice, and enough paperwork to make anyone spiral at 2am. After many sleepless nights stress-Googling things like "Can my dog fly internationally in cabin?" and "Why does every airline have different pet carrier dimensions?", I figured other pet parents were probably suffering too.
So I built this site to make international pet travel easier, clearer, and a little less chaotic. From airline pet policies and in-cabin dog travel tips to tricky destination requirements and relocation checklists, everything here is designed for pet parents trying to navigate flying with a dog — or a cat — without losing their sanity.
Because moving abroad with pets is stressful enough without having to open 14 tabs, cross-reference embassy websites, and decode airline fine print like it's a legal contract.
The route that started it all: London Heathrow → Montreal (overnight) → Miami. Air Canada out of Heathrow, then American Airlines on to Miami — in cabin the whole way. Theo slept for most of it. I did not.
What this site is: a practical, real-world guide to pets in cabin travel — which airlines actually allow it, what paperwork each country needs, which routes work and which don't, and the workarounds when your destination makes it difficult (looking at you, UK).
What this site isn't: a substitute for checking the airline's current policy directly before you book. Rules change. I update things when I find errors, but always verify. (If you're curious how the information here gets checked in the first place, there's a how we check page.)
Who it's for: anyone trying to figure out how to fly internationally with a small dog or cat in the cabin — without the 14-tab spiral.
Got a route that's not covered, found an error, or just want to share how your trip went? Get in touch — I genuinely read everything.
Pets in Cabin is free, ad-free and built by one person. If you'd like to leave a tip, there's a coffee button below — totally optional, and the guide is the same either way.
