Carry-on dimensions change from one airline to the next, the 100ml liquids rule is quietly collapsing across parts of Europe, and Brazil's ANAC just rewrote the power bank law. The honest guide so you don't find all this out at the security scanner.

Standard carry-on: roughly 55 x 35 x 25 cm (22 x 14 x 10 in) and up to 10 kg (22 lb) — but some airlines already allow 12 kg (26 lb) on many fares. The personal item (a backpack or bag that fits under the seat) measures up to about 45 x 35 x 20 cm and counts separately.
Liquids rule: 100ml (3.4 oz) per container, all inside a single 1-litre resealable clear bag. It applies on international flights; many domestic markets don't enforce it.
New for 2026: dozens of European airports (Heathrow, Gatwick, Rome Fiumicino, Milan Linate, Dublin, Prague T2) have scrapped the 100ml limit thanks to new CT scanners. It's a patchwork — don't assume, confirm at your departure airport.
Power bank rules tightened in 2026: max 2 per passenger, always in your carry-on, up to 100 Wh allowed freely, and charging the device onboard is banned.
Never check: power banks, loose lithium batteries, laptop, camera, essential medication, documents and keys. Sharp objects and liquids over 100ml go in the hold only.
