Spirit Airlines Pet Policy

Selected official pet-carriage conditions; route and service coverage is shown below.

Carrier and crate dimensions

Dog / Cat · In the cabin

Official contract permits ordinary domestic cabin pets, not international cabin pets. Carrier ≤45.72 ×35.56 ×22.86 cm (L/W/H), fits underseat and allows standing/turning. One carrier per guest, up to two similar pets per carrier, six carriers per aircraft. Carrier counts as carry-on; pet stays inside.

Selected official conditions only, for the operating airline and the direction, aircraft, service and dates stated in each rule. A mode tab may contain a prohibition or unresolved condition; it does not grant carriage. Obtain actual pet space approval and origin/transit/destination clearance separately. Assistance animals, commercial movement and unlisted services need separate assessment.
