Yes, you can generally take calipers on an airplane, but with some important restrictions.
Carry-On vs. Checked Baggage
The key factor in determining whether you can bring calipers on an airplane is their size and whether they are in your carry-on or checked luggage.
Carry-On Baggage
- Small tools with a head and shaft measuring 6 cm (2.4 in.) or less (measured from the joint to the tip) are permitted in carry-on luggage. This includes many types of calipers.
- If your calipers meet this size requirement, you should be able to take them in your carry-on bag.
- Larger calipers are generally not allowed in carry-on bags and must be placed in your checked baggage.
Checked Baggage
- There are typically no restrictions on the size of calipers in checked baggage.
- You can pack your calipers in your checked luggage without concerns about size restrictions.
Considerations
Here are some additional considerations when traveling with calipers:
- Sharp Points: Be aware of the sharp points on some caliper models. While not considered a weapon, security may want to inspect them more closely.
- International Travel: Regulations can vary by country. It is always best to check the specific rules of the airports and airlines you will be traveling with.
- TSA Discretion: Even if your calipers meet the size requirements, TSA agents have the final say. They may ask to inspect them more closely, especially if they appear suspicious.
- Protect Your Calipers: When packing calipers, especially in checked bags, protect them to avoid damage. A sturdy case or padding is recommended.
