Your gate-day checklist
You have a fit — here’s how to actually fly in-cabin
Four things to line up before travel day, then the one purchase that makes the rest possible: a carrier built to fit under the seat.
General gate-day guidance — not any airline’s live policy. Pet rules, fees, and paperwork change often, so confirm each step on your airline’s official pet page before you fly.
- 1
Book your pet’s cabin spot now
Cabins cap how many animals fly per flight, and they sell out. Reserve the pet slot as soon as you book your own seat — by phone if the site won’t let you add it online.
- 2
Carrier stays under the seat in front of you
Your pet rides on the floor, under the seat, for the whole flight — not on your lap, a tray, or an empty seat. Skip bulkhead and exit rows, which have no under-seat space.
- 3
Pack the health papers your destination requires
Bring the rabies record and any health certificate (CVI) your route needs — printed copies in your carry-on, not just photos. Some checkpoints and airlines want the originals.

No food for ~4 hours before; water up to boarding
An empty stomach cuts down on accidents and nausea in the air. Line the carrier with an absorbent pad and pack a collapsible bowl for long layovers.
Get an airline-approved carrier
This is the step everything else depends on. You need a soft-sided carrier that compresses to the under-seat space your airline allows and lets your pet stand and turn around. These stores carry cabin-rated carriers with the dimensions listed:
