Super Glue
Non-flammable super glue in a small tube is allowed under the standard 3.4 oz liquids rule, but flammable adhesive formulas are banned from both carry-on and checked bags.

Carry-on details
Allowed only if it's non-flammable and small. Most household super glue tubes are non-flammable and fine as a liquid/gel: the tube must be 3.4 oz (100 mL) or less and fit in your one quart-size clear bag with your other liquids. Some industrial-strength or specialty cyanoacrylate formulas are flammable — check the label or safety data sheet (SDS) for a flash point at or below 140°F (60°C), which means it's banned entirely.
Checked-bag details
Allowed only if it's non-flammable. A non-flammable super glue can go in checked baggage without the 3.4 oz limit that applies to carry-on, but pack it upright and sealed to prevent leaks. A flammable adhesive is a prohibited hazardous material and cannot be checked either — it simply cannot fly.
Quantity limit
100 ml (per container)
Special instructions
If you're unsure whether your glue is flammable, check the manufacturer's product label or safety data sheet (SDS) for the flash point. A flash point at or below 140°F (60°C) means the product is flammable and prohibited in both carry-on and checked bags.
