When flying, passengers must adhere to the TSA's strict regulations on firearms and gun cases. The TSA requires that firearms be stored in a lockable, hard-sided container that was designed to store firearms. The lockable container should be the exclusive owner of the key or combination. There are various available hard-sided rifle cases that are TSA-approved and hence suitable for plane travel. The locks on these cases are usually very strong, and the cases themselves are usually composed of metal or high-impact plastic. The following are some rifle cases that have been approved by the TSA: Pelican 1750 Rifle Case SKB iSeries Roto Military Rifle Case Plano All Weather Tactical Gun Case Monoprice Hard Case for Rifles Even if your firearm case is locked, the TSA may access it and check it as part of the screening process. Because of this, it's preferable to pack your firearms in a method that allows for simple access for examination and to select a case that can be quickly opened and closed.
