About
Spinning Jack tells you whether your dog or cat can actually fly, before you book anything. You give the pet. We give the verdict.
Most travel tools start with the route. You pick where you want to go, then find out at the worst possible moment that your dog is too heavy for the cabin, the breed is banned, or the country needs a document that takes four months to get. Spinning Jack flips that around. You start with the animal sitting next to you, and the search works outward from there.
You enter three things: species, breed, and weight with the carrier. Spinning Jack checks that pet against the published pet policy of every commercial airline on the route and returns a clear verdict for each one. No reading twelve airline pages in twelve tabs. No guessing whether 8 kilos counts as in-cabin or cargo. Just an answer.
The airline accepts your pet in the cabin on this route, within the published weight and carrier limits.
Allowed, but with a catch: a breed restriction, a seasonal embargo, a fee per segment, or a document you need in advance.
This airline will not carry your pet on this route, usually a weight ceiling, a banned breed, or no cabin option at all.
Each verdict carries the detail behind it: the pet fee, the carrier dimensions, the in-cabin weight limit, and any breed rule. Snub-nosed breeds like French Bulldogs and Persian cats get flagged separately, because brachycephalic animals face real heat-stress risk in the air and several airlines restrict them.
An airline saying yes is not the same as a country saying yes. A dog can be cleared for the cabin and still be turned away on arrival because the rabies titer test was drawn one day too early, or the microchip was registered after the vaccination instead of before. So Spinning Jack covers the second half too: pet entry requirements by country, the documents involved, and how far ahead you have to start.
That is where the timelines bite. A USDA APHIS health certificate has a short validity window. A rabies titer test for places like Australia, New Zealand, Japan, or Hawaii can stretch the full process close to nine months. Finding that out before you book is the entire point.
For the person flying with a dog or cat who wants a straight answer instead of a forum thread from 2019. For the owner relocating across borders who needs to know which carrier accepts the pet and which documents the destination demands. For anyone who has ever typed "can my dog fly on this airline" into a search box and gotten everything except a yes or a no.
Spinning Jack is a Jack Russell terrier, the kind of dog that spins in a tight happy circle when something good is about to happen. He is the face of the tool and, more practically, the thing you ask. When the verdict comes back cleared, he spins. It is a small joke that happens to be the whole brief: you should feel that certain before you fly with your animal.
The data underneath is less playful. Every airline policy is normalized into one schema, verified against the carrier's own published rules, and dated to the day it was last checked. Airlines change pet policies often and quietly. We track them so the verdict you get is the one that is true today, not the one that was true last year.
