Banned on a plane: explosives, fuels, fireworks, strong chemicals, and many weapons; others face strict carry-on or checked-only limits.

Carry-on baggage bans include liquids over 3.4 oz, flammables, weapons, many sharp tools, and spare lithium batteries over set limits.

Checked baggage bans spare lithium batteries, power banks, e‑cigs, fireworks, gasoline, strong chemicals, unsecured lighters, and loaded firearms.

Carrying cosmetics on a plane means liquids in 3.4‑oz containers inside one quart bag; solids and powders are fine, and aerosols must meet size limits.

Cosmetics in carry-on follow the 3-1-1 liquids rule; checked bags allow full-size items, but aerosols, flammables, and sharp tools have extra limits.

Yes, you can bring a wheelchair on a plane, with airline handling rules for stowage, batteries, and assistance steps.

No, weed vapes with THC aren’t allowed on planes; only an empty device rides in carry-on, and rules shift by route.

TSA item list rules in short: 3‑1‑1 for small liquids, spare lithium batteries in carry‑on only, and solid food fits in either bag.

Yes, you can bring a folding wagon on a plane, but it usually must be gate-checked or checked; in-cabin carry for a wagon is rare.
