Yes, you can take muscle rub on a plane, but how big a container you can carry in your hand luggage now depends on which airport you fly from. Most UK and Irish airports still use the long-standing 100ml limit, while a growing number with new CT scanners, including Heathrow, Gatwick, Birmingham, Edinburgh, Bristol and both Belfast airports, now allow containers up to 2 litres. Because the rules vary and keep changing, the safe move is to pack to 100ml unless your specific departure airport clearly says otherwise. A 50ml travel size clears every airport with room to spare, which is exactly why I started carrying one.
- Liquid limits now vary by airport: many are still 100ml, some allow up to 2 litres
- A cream, gel, roll-on or balm all count as liquids for security purposes
- The size printed on the container is what security checks, not how much is left inside
- Your return or transfer airport may use a stricter rule than your departure airport
- A 50ml travel size stays within the limit at every airport, so you never have to check

Can You Take Muscle Rub on a Plane?
You can take muscle rub through airport security in your hand luggage, and how large a container is allowed depends on your airport's liquid limit. Muscle rubs are treated as liquids at security whether they are a cream, gel, roll-on or balm, so they follow the same rule as your shampoo or moisturiser. At most airports that limit is still 100ml per container; at airports with the newer CT scanners it can be as much as 2 litres. Anything above your departure airport's limit has to travel in your checked hold luggage instead.
I fly a few times a year to courses and events, and I learned the practical side of this the hard way, by having a full-size bottle taken off me at security once. Now I keep a travel size in my bag and never have to think about which rule is in force. For the official baseline, the UK government's hand luggage guidance sets out the liquid rules, and it notes that while most airports still cap containers at 100ml, some now allow up to 2 litres.
The Liquid Rules in 2026: It Depends on Your Airport
There is no longer one single UK liquid rule. New CT scanners produce a detailed 3D image of your bag, so where they are installed and approved, staff can clear larger containers without opening anything, and those airports have lifted the limit to 2 litres. Where the older scanners are still in use, the familiar 100ml rule applies. The rollout has run behind schedule and the limit has even been switched back at times, which is why two airports of similar size can have completely different rules on the same day.
One point that catches people out: having a new scanner does not automatically mean a 2-litre allowance. Several airports have installed the 3D scanners, so you can leave liquids and laptops in your bag, yet still enforce the 100ml container limit while they wait for regulatory sign-off. So the presence of fancy scanners is not your cue to pack a big bottle. The airport's own published rule is.
Always check your specific airport's official website before you fly. These rules change airport by airport and at short notice, and the airport's own security page is the only source that is reliably current. The lists below were last checked on 25 July 2026, but treat them as a starting point, not the final word, and let airport signs and staff instructions on the day be the authority.
Which Airports Allow 2 Litres, and Which Still Use 100ml
Based on official airport guidance checked in July 2026, here is where things stand. At the 2-litre airports you can also usually leave liquids loose in your cabin bag rather than using a clear plastic bag. At the 100ml airports many now let you keep liquids in your bag too, but the 100ml container size still applies.
| Liquid limit | Airports (per their official guidance, July 2026) |
|---|---|
| Up to 2 litres per container | Heathrow (all terminals), Gatwick, Birmingham, Edinburgh, Bristol, Belfast City, Belfast International |
| Still 100ml per container | Manchester, Stansted, Luton, London City, East Midlands, Newcastle, Leeds Bradford, Liverpool, Glasgow, Aberdeen, Cardiff |
This is not every UK and Irish airport, and rules are changing regularly. If your airport is not listed, or you want to be certain, check its official security page before you pack anything larger than 100ml.
Do Not Forget Your Return Flight
The rule that matters is the one at the airport where you are screened, so your outbound airport is only half the decision. A 500ml bottle you were allowed to bring through Heathrow can be refused on the way home if your return or transfer airport still uses the 100ml limit. This is the single most common way people get caught out by the new rules, and it is a strong argument for simply packing small in the first place. Plan around the strictest airport on your whole journey, not the most generous one.
What About a Big Bottle That's Nearly Empty?
At a 100ml airport, a container over 100ml is not allowed in hand luggage even if it is nearly empty, because security judges it by the size printed on the container, not by how much product is left inside. A 200ml bottle with a few millilitres in the bottom is still a 200ml bottle to the person at the scanner. People assume a half-used tub will be fine, and it gets taken off them at the gate.
If the only rub you own is a large one and you are flying from a 100ml airport, your choices are to pack it in your hold luggage, decant a small amount into a proper travel bottle of 100ml or less, or simply buy a travel size that stays within the limit everywhere.
Muscle Rub in Checked Hold Luggage
There is no liquid size limit for muscle rub in checked hold luggage, so a full-size bottle travels fine in the case you check in, whichever airport you use. The only sensible precaution is to make sure the lid is fully closed and ideally to seal the container in a small freezer bag, because cabin pressure changes and rough handling can occasionally loosen a cap. If you only ever use your rub at your destination and not during the journey, the hold is the easy answer. If you want it on you during the flight itself, it has to meet your airport's hand luggage limit.

Why Take Muscle Rub When You Fly at All?
Long periods sitting still in a cramped seat leave a lot of people stiff through the lower back, neck and legs, and a cooling menthol cream gives a genuinely welcome distraction from that stiffness while you move around and stretch. To be clear about what it does and does not do: a cooling cream is a comfort measure, not a treatment, and it is no substitute for the things that actually matter on a long flight, getting up to walk regularly, keeping your ankles moving, and staying hydrated. If you have any medical concern about swelling or pain in your legs after flying, that is one to raise with a pharmacist or GP rather than manage with a rub.
Frequently Asked Questions
Can I take muscle rub in my hand luggage?
Yes. Muscle rub counts as a liquid at security whether it is a cream, gel, roll-on or balm, so it follows your airport's liquid limit. That is 100ml per container at most UK and Irish airports, and up to 2 litres at airports with the newer CT scanners such as Heathrow, Gatwick and both Belfast airports. Check your airport's official page, and pack to 100ml if unsure.
Which UK airports allow 2 litres of liquid?
As of July 2026, official guidance shows a 2-litre container limit at Heathrow, Gatwick, Birmingham, Edinburgh, Bristol, Belfast City and Belfast International. Many others, including Manchester, Stansted, Luton and Glasgow, still use the 100ml limit. Rules change often, so always confirm on your airport's own security page before you pack.
Does a new scanner mean I can bring 2 litres?
Not always. Some airports have installed the 3D CT scanners, so you can leave liquids and laptops in your bag, but still enforce the 100ml container limit while they wait for regulatory approval. The scanner alone is not the signal, the airport's published liquid rule is what counts.
Can I bring a large bottle if it's almost empty?
Not through a 100ml airport. Security judges the container by its printed size, not by how much is left inside, so a part-used 200ml tub is still treated as 200ml. Pack it in hold luggage, or use a container within your airport's limit.
Is a 50ml muscle cream allowed on a plane?
Yes, everywhere. A 50ml cream is within the limit whether your airport uses the 100ml rule or the 2-litre rule, and it works the same on your return flight. It is the simplest option if you want your rub on you during the journey rather than packed away in the hold.
