Dairy Free Airline Meal Code
The airline code for a dairy free airline meal is NLML (Low Lactose Meal).
Travelling with lactose intolerance
During your flight
Bring your own milk
Although some airlines will be able to provide you with non-lactose milk along with your dairy-free meal, you might want to bring your own milk onto the flight just in case. You'll be able to bring any liquids that are under the 100ml in your carry-on baggage or — if there is a good choice of shops at the airport — you can purchase it after security.
If you're travelling with a baby that is lactose intolerant, you can bring extra non-dairy milk on the flight to feed them. However, you'll need to screen this separately and they'll likely test with a test strip.
Bring food from home
Unfortunately, not every airline offers non-dairy food options. If you're flying on a short-haul flight, menus are much more limited than on long-haul flights. Luckily, there aren't as many restrictions on flying with food as there are with flying with liquids. This means you can bring your own food onto the flight and not have to worry about a lack of option.
Make Note of the Airport Toilets
It might be useful to make a note of where the airport toilets are in case something unexpected makes you ill. Find a map of the airport as soon as you get there or look on the airport's website beforehand.
During your travels
Lactose Intolerance Pills
Although they aren't always 100% effective, by taking a lactose intolerance pill, you'll be able to consume up to the equivalent of one cup of milk (give or take) without any problems. Lactose intolerance pills give you a bit of leeway and are a great option if you're travelling and don't want to constantly worry about whether the food you've just consumed contains any traces of lactose.
Build Up Your Tolerance Pre-Travel
In the weeks leading up to your flight, train your body to handle small amounts lactose by drinking small amounts of milk before you travel. This will make a reaction less likely if you accidentally consume small amounts of lactose when you're travelling. However, every persons tolerance to lactose differs, so it's important to speak to your doctor before doing this.
