What dog owners should know
Small pets
Dogs and cats under 30 lb in an approved under-seat carrier; published policy lists a $100 one-way pet fee.
Larger dogs
Dogs weighing less than 80 lb may travel leashed on the cabin floor with a purchased adjoining seat, subject to JSX approval.
Checked pets and cargo
Not offered as ordinary pet transport on JSX flights.
Routes
Selected U.S. destinations; verify service on the current route map.
Important: Policies, prices, routes, pet limits, aircraft and availability can change. Always confirm details with JSX before buying tickets. International entry requirements are separate from an airline's acceptance rules.
Before you book
Confirm your dog's eligibility, carrier or restraint requirements, total fare for you and your dog, route-specific restrictions, cancellation terms and whether the flight is confirmed. Ask about documentation, microchips and health certificates for international travel.
