If you have ever searched “Emirates liquid limit” or “Delta carry-on liquids,” here is the short version: they are all the same. The carry-on liquid limit is not set by the airline. It is set by security at the airport you fly from, and almost every airport in the world uses the same 100 ml rule.
That means the answer is identical whether you fly Emirates, Qatar Airways, British Airways or Delta. This guide explains why, shows the rule airline by airline, and covers what genuinely does differ between carriers.

Quick answer
Every major airline uses the same carry-on liquid limit: 100 ml (3.4 oz) per container, inside one clear resealable bag. Airlines do not set this rule, so Emirates, Qatar Airways, Delta, United, British Airways and the rest are identical on liquids. What varies between airlines is cabin bag size and weight, not the liquid limit.

Why every airline has the same limit
Liquids in hand luggage are a security matter, not an airline policy. The screening is run by the security authority at your departure airport — the TSA in the United States, and equivalent agencies elsewhere — and they enforce the international 100 ml standard for everyone passing through, regardless of which airline is printed on the ticket.
For the full breakdown of the limit, what counts as a liquid, and the exceptions, see our guide to the carry-on liquid limit and the 3-1-1 rule.
Carry-on liquid rule by airline
| Airline | Carry-on liquid rule |
|---|---|
| Emirates | 100 ml (3.4 oz) per container, one clear bag |
| Etihad Airways | 100 ml (3.4 oz) per container, one clear bag |
| Qatar Airways | 100 ml (3.4 oz) per container, one clear bag |
| Saudia | 100 ml (3.4 oz) per container, one clear bag |
| flydubai | 100 ml (3.4 oz) per container, one clear bag |
| British Airways | 100 ml (3.4 oz) per container, one clear bag |
| Lufthansa | 100 ml (3.4 oz) per container, one clear bag |
| Air France | 100 ml (3.4 oz) per container, one clear bag |
| KLM | 100 ml (3.4 oz) per container, one clear bag |
| Turkish Airlines | 100 ml (3.4 oz) per container, one clear bag |
| Singapore Airlines | 100 ml (3.4 oz) per container, one clear bag |
| Delta Air Lines | 100 ml (3.4 oz) per container, one clear bag |
| United Airlines | 100 ml (3.4 oz) per container, one clear bag |
| American Airlines | 100 ml (3.4 oz) per container, one clear bag |
| Southwest | 100 ml (3.4 oz) per container, one clear bag |
| JetBlue | 100 ml (3.4 oz) per container, one clear bag |
| Air Canada | 100 ml (3.4 oz) per container, one clear bag |
| WestJet | 100 ml (3.4 oz) per container, one clear bag |
The rule is the same across the board because it comes from airport security. If a list ever shows a different liquid limit for a specific airline, it is almost certainly describing that airline’s cabin bag size or weight allowance, not the liquid rule.
A note for Gulf carriers
Travellers flying Emirates, Etihad, Qatar Airways, Saudia or flydubai often ask whether the Gulf hubs are different. They are not, when it comes to liquids: Dubai, Abu Dhabi, Doha and the other major Gulf airports apply the same 100 ml container limit and single clear bag. Pack your carry-on liquids exactly as you would for any other international flight.
What actually differs between airlines
Where airlines really do vary is everything around the liquid rule:
- Cabin bag size and weight — the biggest difference, and the one most likely to catch you out at the gate.
- Checked baggage rules for larger liquids and alcohol — see our guide to liquids in checked baggage.
- Duty-free handling on connecting flights, which depends on your route and transfer airport.
Before you fly, it is worth checking your airline’s cabin bag allowance and what a checked bag would cost. Our baggage fee calculator can help with the second part.
Frequently asked questions
Does Emirates have a liquid limit for hand luggage?
Yes, and it is the same 100 ml container limit as everyone else. Emirates does not set its own liquid rule. The limit is enforced by security at your departure airport, such as Dubai International, which applies the standard 100 ml and single clear bag rule.
Does Qatar Airways allow liquids in carry-on?
Yes, within the standard 100 ml per container in a single clear bag. As with all airlines, the limit comes from airport security at departure, not from Qatar Airways itself.
Do Delta, United and American have different liquid limits?
No. All US airlines follow the same TSA 3-1-1 rule: 3.4 ounces (100 ml) per container in one quart-sized clear bag. The airline you fly makes no difference to the liquid limit.
Is the carry-on liquid limit different on international airlines?
No. The 100 ml container limit is an international security standard, so airlines in the Gulf, Europe, Asia and North America all follow it. What changes is the airport, not the airline.
So what actually differs between airlines?
Cabin baggage size and weight allowances, checked-bag rules, and how they handle duty-free vary a lot between airlines. The liquid limit itself does not. Always check your airline’s cabin bag dimensions and weight separately from the liquid rule.
