What's allowed (and not) in carry-on hand luggage
The 100ml liquid rule
Liquids, gels and aerosols in hand luggage can only be carried in containers of 100ml or less each, all fitting inside a single transparent resealable bag of no more than 1 liter (about 20×20cm) — one bag per passenger, shown separately at security.
Moldova isn't in the EU, but Chisinau Airport follows the same standard thanks to the EU–Moldova Common Aviation Area Agreement (2012), which extends EU aviation security rules to the country. So flying out of Chisinau means the same rules as any EU airport.
What's not allowed in hand luggage
The standard list, common to most countries and based on ICAO standards and the EU aviation security regulation: knives and blades of any length, scissors with blades over 6cm, razor blades outside their cartridge, box cutters, blunt weapons and bulky sports equipment (bats, clubs), tools longer than ~6cm (screwdrivers, drills, saws), firearms and replicas, ammunition, self-defense sprays (pepper spray and similar), and flammable or explosive items (fireworks, flares, lighter fluid).
What's surprisingly allowed
Baby food and milk in quantities over 100ml — allowed if you're traveling with a child; these liquids need to be declared separately and may be checked at security.
Medication and liquid dietary items needed for medical reasons, over 100ml — also allowed; it's a good idea to carry a prescription or doctor's note.
Duty-free liquids bought airside or on board, over 100ml — can pass through security at a connecting airport if sealed in a tamper-evident bag with a visible receipt (usually within 48 hours of purchase); in practice, some non-EU airports may check this more strictly.
Cabin bag size rules vary by airline

The liquid and prohibited-item rules are based on the EU aviation security regulation (Regulation (EU) 2015/1998) and IATA guidance — rewritten here in our own words as they apply to flights from Chisinau Airport.
