If you have a peanut allergy, you may see the code PNUT associated with your airline booking. The PNUT airline code is a Special Service Request, or SSR, code used in airline reservation systems to identify a passenger with a peanut allergy, particularly an allergy involving peanut dust.
The code can help communicate an allergy to airline and airport staff, but it is important to understand its limits. Having PNUT on your booking does not automatically make the aircraft peanut-free, guarantee an allergen-free meal or prevent other passengers from bringing peanuts on board.

This guide explains what PNUT means, how it differs from an airline meal code and what passengers with peanut allergies should confirm before flying.
What Does the PNUT Airline Code Mean?
PNUT is an airline SSR code associated with a passenger who has a peanut allergy.
SSR stands for Special Service Request. A SSR code is there for a code which refers to a specific special service request. These short codes are placed within airline reservations to communicate particular passenger needs or services between reservation systems and operational staff.
The PNUT SSR code therefore functions as an allergy-related service code rather than a description of a particular meal.
For a wider overview, our guide to airline allergy codes explains other meal and SSR codes related to allergies that passengers may encounter.
Is the PNUT Airline Code a Special Meal Code?
No. The PNUT code should not be confused with a special meal code.
Meal codes such as VGML, GFML or NLML identify a particular category of airline meal. PNUT communicates an allergy-related requirement or passenger information within the booking. This distinction matters because having PNUT recorded does not mean that a specially prepared peanut-free meal will automatically be loaded onto the aircraft.
You can read our guide to airline meal codes for an explanation of the codes used for special meals.
What Does the PNUT Code Do on an Airline Booking?
The purpose of the PNUT code is to record and communicate the passenger’s peanut allergy within the airline reservation and operational process. Exactly what happens after the code is added depends on the airline. An airline may use the information to alert relevant staff, change its onboard snack service, offer pre-boarding or apply another allergy procedure.
Does Using the PNUT Code Guarantee a Peanut-Free Flight?
No. Using the PNUT airline code does not guarantee that an aircraft will be completely free from peanuts. Airlines generally cannot control every food item brought onto an aircraft by other passengers. Residue from previous flights may also remain on seats, tray tables or other surfaces.
Even airlines that change their own catering because of a peanut allergy may state that they cannot provide a completely allergen-free cabin.
If your allergy is severe, read the airline’s current allergy policy before booking rather than assuming that the presence of the PNUT code on your booking provides a particular level of protection.
Does PNUT Mean the Airline Will Stop Serving Peanuts?
Not necessarily. Airline policies differ.
Some airlines may stop serving peanuts or peanut products when notified about an allergy. Others may not normally serve peanuts anyway, while some carriers may have different procedures for nuts and other allergens.
Ask your airline exactly what it does after a peanut allergy is recorded. Do not rely on another airline’s policy or an experience from a previous flight.
Will the Airline Make a Peanut Allergy Announcement?
An onboard announcement is not guaranteed simply because the PNUT airline code is attached to a passanger booking.
Some airlines may ask nearby passengers or the wider cabin to avoid eating nuts, while others do not make allergy announcements. Even where an announcement is made, the airline cannot guarantee that every passenger will comply or that nobody has brought peanut products onto the aircraft.
Check the airline’s current policy and ask what accommodations are available for your circumstances.
Can Using the PNUT Code Give You Pre-Boarding?
Some passengers with severe food allergies may be allowed to pre-board so they have time to clean their seating area before other passengers arrive. This is a fairly common adjustment that airlines may make for passengers with allergies.
This is particularly relevant in the United States, where disability-related pre-boarding rules can apply to passengers who need additional time to prepare their seating area because of a severe allergy. For mroe about travelling in the United States, our dedicated guide holds a whole host of travel information.
Airline procedures vary internationally. If wiping your seat, tray table and surrounding surfaces is part of your allergy management plan, contact the airline before travel and ask whether early boarding is available.
How Do You Add the PNUT Code to a Flight Booking?
The method depends on the airline. You may be able to declare an allergy while booking, through Manage My Booking or by contacting the airline’s accessibility, medical or special assistance team. You do not need to know the code PNUT before contacting the airline. Tell the airline clearly that the passenger has a peanut allergy and describe the support required.
Ask the agent to confirm what has been recorded in the reservation and what practical arrangements the airline will make. If your itinerary changes, check that the allergy information remains attached to the new flights.
When Should You Tell the Airline About a Peanut Allergy?
Contact the airline as early as practical, particularly if you need a specific accommodation.
Do not wait until the aircraft doors are closing to mention a severe allergy for the first time if you could reasonably have notified the airline earlier. Advance notice gives you time to understand the airline’s policy and decide whether it meets your needs.
It is also sensible to remind staff at check-in, the gate and on board where appropriate. This should complement advance notification rather than replace it.
The PNUT Airline Code vs a Peanut-Free Meal
Using the PNUT SSR code and a special meal request solve different problems.
The PNUT airline code communicates a peanut allergy.
A special meal request asks the airline to load a particular type of meal. Not every airline offers a dedicated nut-free or peanut-free meal, and a meal described as avoiding nuts may still carry warnings about cross-contamination.
Learn more about the ALML meal code that you might find on a meal prepared for someone with a food allergy.
The PNUT Airline Code vs the PFML Airline Meal Code
The PNUT code can easily be confused with the PFML code because both can appear in discussions about airline food and specifically peanut-allergic travellers.
PNUT is an SSR connected with peanut allergy.
PFML is a peanut-free meal code used in some reservation and catering systems.
The availability of PFML is not universal, and requesting a meal does not automatically create an allergen-free aircraft environment. Our guide to the PFML meal code explains that code in more detail.
What if You Have a Tree Nut Allergy as Well?
Peanuts and tree nuts are different allergens. If you are allergic to both, tell the airline explicitly rather than assuming that the PNUT peanut allergy code communicates every nut allergy.
Explain which foods you need to avoid and ask how the airline records multiple allergies. Airline terminology and procedures can differ, so clear written information is useful.
Can You Bring Your Own Food if PNUT Is on Your Booking?
Passengers can generally bring suitable solid food through airport security anyway, although security restrictions apply to liquids, gels and similar foods. Destination customs and biosecurity rules can also restrict which foods may be carried across a border.
For a severe allergy, bringing familiar food can reduce reliance on airline catering. Check airport security and destination import rules before packing. Keep ingredient labels where possible and pack enough suitable food to account for delays, particularly on long journeys or connections.
If you have to travel with extra food because of an allergy, it would be worth researching medical luggage and asking the airline if you qualify for bringing extra luggage with safe food inside.
Should You Carry EpiPens When Flying With a Peanut Allergy?
If you have been prescribed adrenaline auto-injectors, carry them according to the advice given by your healthcare professional. Essential emergency medication should be accessible in the cabin rather than placed in checked baggage.
Carry the number of devices recommended for you (in the UK the standard is to have 2 EpiPens on you at all times) and check documentation requirements for your airline and destination. You may find it helpful to have a dedicated folder in a Google Drive to store copies of any medical and allergy paperwork so you can access it when you travel.
Our guide to flying with EpiPens covers practical considerations for travelling with adrenaline auto-injectors and our wider guide to travelling with allergies covers range of allergy travel topics.
What the PNUT Airline Code Does Not Guarantee
- A completely peanut-free aircraft.
- A peanut-free or allergen-free meal.
- That other passengers will not bring peanuts on board.
- That an announcement will be made.
- That every airline will provide the same accommodation.
- That the cabin has been specially deep-cleaned before your flight.
- That PNUT also covers every tree nut or other food allergy.
This is why the code should be treated as part of communication with the airline rather than as a complete allergy-management plan.

FAQs About the PNUT Airline Code
What does PNUT stand for on a flight booking?
PNUT is an airline Special Service Request code used to identify a passenger with a peanut allergy, commonly described in industry code lists as an allergy to peanut dust.
Is PNUT an IATA meal code?
PNUT is an SSR used in airline reservation processes rather than a standard special meal request such as VGML or GFML. Its purpose is to communicate a peanut allergy rather than order a specific meal.
Does PNUT mean my flight will be nut-free?
No. Airlines generally cannot guarantee a completely peanut-free or nut-free aircraft because other passengers may bring food on board and residue may remain from previous flights.
Is PNUT the same as PFML?
No. The PNUT code communicates a peanut allergy, while PFML refers to a peanut-free meal in systems where that meal option is available.
Can I ask an airline to add the PNUT code to my booking?
Tell the airline that you have a peanut allergy and ask it to record the appropriate information. The exact code and process used can depend on the carrier and reservation system.
Do I still need to tell cabin crew if PNUT is on my booking?
It is sensible to follow the airline’s instructions and remind appropriate staff on the day of travel, particularly when you have requested a specific accommodation. Do not assume every member of staff has seen every detail in your reservation.
The PNUT SSR code can be useful for recording a peanut allergy or related request on an airline booking, but seeing PNUT on your reservation does not mean that every possible allergy precaution has automatically been arranged.
Airline allergy policies vary considerably, including what information can be added to a booking, whether pre-boarding is available for cleaning the seating area, what announcements may be made and how food is handled onboard. It is therefore important to check the individual airline’s current policy and confirm exactly what support has been agreed before you travel.
If the PNUT code has been added to your booking, check that the information recorded by the airline accurately reflects your needs. It is also worth reconfirming the request after a flight change, rebooking or other significant change to your itinerary.
Most importantly, continue to follow your usual allergy management plan when travelling, including carrying prescribed emergency medication and bringing suitable food where necessary.
