What it covers
Trips from the mainland U.S. to Canada, France, Hawaii, Italy, Japan, Mexico and United Kingdom (Great Britain), plus flights within the mainland U.S., on the 26 airlines in our airline comparison. It covers dogs traveling as pets with their owner; puppies traveling alone, commercial moves and service dogs follow other rules.
How the dates work
- The checker plans from scratch: each step gets the latest date it can be done, counted back from your flight (and, for certificates, the earliest). If you've already done a step, compare it with its “Already done?” note.
- Where a rule says “more than” a number of days, or counts full days from the day after, the dates include that extra day, so they never cut it close.
- Where official sources disagree, the checker says so and shows both, rather than picking one for you.
- Values an airline or authority doesn't publish show as “not verified”, never as a guess.
Before you rely on it
Entry rules and airline policies change, sometimes with little notice. The checker is a planning aid built from the official pages linked in each result. Confirm the current requirements with your vet, USDA APHIS and your airline before you book or travel. See how we verify our data.
