Carry-on details
Allowed with conditions. Whether it comes in an aerosol can or a pump/liquid bottle, setting spray counts as a liquid. Each container in carry-on must be 3.4 oz (100 mL) or less and fit in your one-quart liquids bag.
Checked-bag details
Allowed, but the format matters. A pump-spray (non-aerosol) bottle has no size limit in checked baggage. An aerosol can is treated as hazmat and is capped at about 500 mL (18 oz) per can, with a combined limit of 2 L (70 oz) of aerosols/liquids per passenger, and the nozzle must be protected from accidental discharge.
Quantity limit
3.4 oz (per container)
Special instructions
If it's an aerosol can, keep the protective cap on the nozzle to prevent accidental discharge in your bag.
