I’m sure you want to bring some extra snacks on a plane, but can you bring a sandwich on a plane?
Here is the short answer:
Yes, you can bring a sandwich on a plane, the TSA allows all types of solid food, including sandwiches, in both carry-on and checked bags. Just keep in mind that sauces or spreads like mayo or jelly must be under 3.4 oz / 100 ml.
In this guide, I will explain TSA rules, tips for packing a sandwich, and what to know if you’re flying internationally.
Let’s dive right in.
| Sandwich | Allowed in carry-on bag | Allowed in checked bag |
|---|---|---|
| Subways sandwich | Yes | Yes |
| MCdonald’s sandwich | Yes | Yes |
| Turkey sandwich | Yes | Yes |
| Homemade sandwich | Yes | Yes |
| Peanut butter sandwich | Yes | Yes |
| Jelly sandwich | Yes | Yes |
What Is The TSA Rules For Sandwiches in Carry-On Bags?
The TSA (Transportation Security Administration) checks what items you can and can’t take through the security checkpoint for flights within and from the U.S.
This is a screenshot from their website stating that sandwiches are okay to bring in both carry-on and checked bags.
This includes any kind of sandwich, like:
- Turkey sandwich
- PB&J sandwich
- McDonald’s burger
- Subway sandwich
- Homemade sandwich
Just keep in mind that spreads like mayo or sauces are no more than 3.4 oz / 100 ml if they’re in a container.
What About Mayo or Peanut Butter?
You can bring spreads like mayo, peanut butter, or jelly, but only in small quantities, as they are considered liquids according to TSA.
The TSA only permits 3.4 oz / 100 ml per container of liquid, paste, or gel in your carry-on.
That includes:
- Salad dressing
- Hummus
- Cream cheese
- Nutella
You need to place them inside a clear quart size bag.
Still Confused? Let TSA Explain
I went deeper to find more answers on X (formerly Twitter) and here is what I’ve found.
Lilith wanted to bring this leftover sandwich on the plane.
The AskTSA replied that sandwiches are good to go on board the plane.
This is also an exchange on X where a passenger asks if he can walk through the TSA with a large NYC bodega style Italian combo sandwich.
The AskTSA team replies that solid food, including sandwiches, is allowed in carry-on bags and says.
This is also a Tweet from a passenger not happy that United Airlines do not gave him any food in a 5+ hour flight.
United Airlines replies that meals are no longer included in ticket prices and that passengers need to bring their own snacks or sandwiches on board.
Can I Eat My Sandwich During a Flight?
Yes, In fact, I always bring a Grilled Cheese Sandwich to enjoy on my long flights.
So you can eat your sandwich on the plane, just take it out of your bag before takeoff.
It’s smart to pack it in a sandwich bag or a small container, this keeps it fresh and makes it easy to take it out if the TSA officer asked.
Can I Put a Sandwich in My Checked Bag?
You can put a sandwich in your checked bag.
But it’s not a good idea, your sandwich could get smashed or spoil if your flight is long.
It’s better to keep it with you in your personal item or carry-on bag, and you can enjoy it if you feel hungry during your flight.
Can I Bring a Homemade Sandwich on a Plane?
Yes, you can bring a homemade sandwich.
In fact, it’s even better than buying food at the airport.
You know what’s in it, it’s usually fresher, and it saves you some money to use it later.
This is a great idea if you’re flying with kids or don’t like airplane meals.
Can I Bring a Sandwich on an International Flight?
Yes, you can bring a sandwich on international flights, but there are rules if you are planning to bring that food into the country.
Most countries are very strict about meat and dairy.
Here’s a quick look at the rules in some places:
| Country | Meat Sandwich | Cheese Sandwich |
| United States | Allowed, check source country | Allowed (solid cheese only) |
| Canada | Allowed if packed well from U.S. | Allowed if labeled and small |
| Mexico | Not allowed | Not allowed |
| United Kingdom | Not allowed | Not allowed |
| Europe (EU) | Not allowed | Not allowed |
| South Korea | Not allowed | Not allowed |
It’s best to eat your sandwich before you land.
If you’re not sure about a country’s rules, check their customs website before you travel.
Final Thoughts:
If you’re flying within the U.S., you can bring any kind of sandwich in your carry-on or personal item bag.
Just follow the TSA 3.4 oz / 100 ml liquid rule for sauces and spreads.
It’s best to pack it neatly so it doesn’t get messy during screening.
On international flights, be careful with meat or dairy.
Most countries might not allow you to bring these items through customs, so eat your sandwich during the flight to avoid any issues later.
I hope this helps
Happy travels
