Flying with a dog or cat on JetBlue

JetBlue publishes 17 × 12.5 × 8.5 in for a soft-sided carrier under the seat. That is the number that decides whether you get on the plane. Everything below was read on the JetBlue policy page, and the link to it is at the bottom.

The one to watch on this airline

The 8.5-inch ceiling is the joint lowest here, and the 20 lb limit includes the bag itself.

Which of our carriers fits under the seat on JetBlue

Measured against 17 × 12.5 × 8.5 in. Length and width have to clear as published. Height gets one inch of give, because a soft side compresses — and no more than one.

Right now, nothing we sell clears this one. JetBlue publishes 17 × 12.5 × 8.5 in, and nothing in our catalogue clears all three of those numbers. We could list you something close and let you find out at the gate. We would rather tell you here.

We are actively looking for a carrier that fits. If you want an email the day we find one, the checklist sign-up at the bottom of this page is the fastest way to hear about it — or write to us with your pet's measurements and we will tell you honestly whether anything on the market works for this route.

Your other bags

The carrier and pet count as one personal item.

The lowest published height on the list at 8.5 inches. Wide, but very shallow.

Policies change without notice, and the airline's own page is the authority — not this one. Read the JetBlue pet policy, or go back to the full guide covering all nine airlines.
