Reading the fit
What matters for this carrier
- Soft-sided: the top and sides can flex slightly to help a borderline under-seat fit.
- Published external dimensions 19.7 x 9.8 x 9.8 in.
- Weight and breed rules are set by the airline and your pet, not the carrier. We do not advise on fitness to fly.
