Can methanol be transported on a commercial aircraft?
For domestic air shipments, maximum allowable package sizes are 1 liter net per package to be transported within the baggage compartment of a passenger aircraft, and 60 liters net per package for cargo aircraft, each “packed in strong outer packaging”. These exemptions are waived and methanol can be carried in the passenger compartment of a commercial aircraft, if the methanol is in an aqueous solution of no greater concentration than 24%.
