Before the checkpoint
Three calls that matter
No, if it is 7 inches or shorter. A longer wrench or pair of pliers gets pulled to checked at the checkpoint.
Short tools can ride in the cabin. Anything over 7 inches, or a heavy set, is simpler in checked baggage.
The 7-inch limit is measured tip to tip. Borderline tools are the officer’s call, so pack close ones in checked to be safe.
