Yes, you can take deodorant in your Jet2 hand luggage in 2026, but the rules depend on the type of deodorant and the current security restrictions at your departure airport. For aerosols, gels, and roll-ons, these are classified as liquids. Under the standard 2026 UK and EU aviation rules, these containers must be 100ml or less and placed inside a single, transparent, resealable plastic bag that holds no more than one liter. If your aerosol is larger than 100ml (like a standard 150ml body spray), it will be confiscated at security unless you are flying from an airport that has fully transitioned to Next-Generation Security Checkpoint (NGSC) scanners, which allow larger liquids. To be safe, Jet2 recommends sticking to the 100ml rule. However, solid stick deodorants (the dry, waxy kind) are not considered liquids and can be carried in any size without needing to go in the clear plastic bag. Always ensure any aerosol has its cap on to prevent accidental discharge in your bag during the flight.
