Yes, you can take FRE Sweet Nicotine Pouches on a plane. As they are tobacco-free and don't involve any combustion, they're generally allowed in both carry-on and checked luggage. Remember that FRE is not classified as "smokeless tobacco" but as an oral nicotine product, which may not be explicitly mentioned in airline policies. When in doubt, it's best to check with the airline, bus, or train company to see their guidelines around nicotine pouches. Also, always be discreet and considerate of those around you.
