How We Flew Our Allergen-Friendly Food to Hawaii (And It Was 100% Worth It)

We took a week long trip to Hawaii as a family of 7 on a budget with multiple food allergies and brought a lot of food with us. 

If that sounds like a lot to manage — it is. But after years of feeding a family with gluten and dairy sensitivities (plus a daughter-in-law who’s allergic to dairy and nuts), we’ve figured out how to make travel work without blowing the budget or spending half our vacation hunting for food everyone can actually eat.

The answer? We brought our own. Frozen meals, packaged snacks, and breakfast staples — all on the airplane. It took a day of prep before the trip, but it saved us hundreds of dollars and so much mental energy once we were there.

No scrambling to find a restaurant that could handle multiple allergies. No spending $150+ every meal to eat out. No reading every menu twice. No “well, you can probably just eat this” moments. Just food we trusted, already made, ready to pull out of the fridge.

Here’s a full breakdown of why we do this, how we fly with food (yes, through security and everything), exactly what we packed, and what we ate all week.

Why Do We Bring Our Own Food to Hawaii?

Honestly, it comes down to three things: allergies, time, and money.

My daughter-in-law is allergic to dairy and nuts. Several of us are gluten- and dairy-sensitive. When you’re managing real dietary restrictions in a group, eating out every meal quickly becomes complicated — especially somewhere like Hawaii where food is pricier and allergy-aware options aren’t always easy to find.

Bringing our own food meant:

• No hunting for restaurants that could accommodate multiple allergies at once
• No wasting vacation time figuring out where everyone could eat
• Real savings on food costs for the whole week – we saved so much $$$ bringing our food!
• More time adventuring — which is the whole point

It also means I know exactly what’s in every meal. When you have a true allergy in the group, that peace of mind is worth a lot.

Wait — You Brought All That Food on an Airplane??

Yes. And I’ve done this dozens of times.

The key is an insulated cooler bag — I use this one from Amazon and it’s the one I’d recommend for a trip like this. It’s big enough to hold a serious amount of food and fits as a carry-on, so it travels with you rather than getting checked.

Here’s the method: freeze everything before you pack it. When your food is frozen solid, nothing registers as a liquid — so it moves through TSA without any issues. Frozen food stays cold longer, too, which means it’s still good when you land and get to your rental.

My cooler gets checked at security pretty regularly. And every single time, the agents look through it and send me on my way. Sometimes they ask a question. Sometimes they just nod. I have never — not once — had food taken away. Honestly, they usually are just impressed.

I have and love these ice packs that freeze quickly and are nice and flat that I line the edges of my cooler with:

A few practical notes:

• Freeze everything completely the night before your trip
• Ice packs are allowed if they’re fully frozen (slushy = may get flagged). I pack my cooler right before I go to the airport so everything is still nice and solid. Don’t do it the night before!
• Organize your cooler so it’s easy to look inside if they need a closer look
• Carry it on — don’t check it — so it stays with you
• Use containers that are easy to stack. If I’m traveling a few states over, I’ll often use glass ones with lids. But, for a longer trip to Hawaii, I used these disposable ones that I could toss along the way. Using containers of the same size make it a whole lot easier to pack your cooler!

For a full deep-dive on flying with food and all our travel snack favorites, check out the Gluten-Free Dairy-Free Travel Guide HERE.

We packed a carry-on cooler bag, two carry on suitcases, and half of one checked bag with food in total. We have Southwest credit cards that get us a free checked bag still per person. If you don’t get that, you may need to do the math on how much food is worth bringing. 

What Food Did We Bring?

Two categories: prepped meals that were frozen, and packaged snacks and pantry items.

Prepped & Frozen Meals:

• Protein blueberry muffins and banana muffins – Made ahead and frozen. I put these in meal prep containers, not Ziploc bags, so they don’t get smushed! A great protein grab-and-go option. 
• Street corn pasta salad – One batch in multiple containers, with rotisserie chicken added so it was a complete meal. Perfect for lunches on the go as we flew and adventured!
• Italian Pasta Salad – One of my favorites that is full of protein and veggies. Same as above on portability and purpose. 
• Chicken avocado salad – Recipe from my Cookbook that we scooped with a chip and ate on the plane for lunch. We ate this one first since the avocados are more perishable than the pasta salads. My Southwest Chicken Salad would also work well here. 
• Honey Chipotle Chicken – I made a whole tray of chicken in a triple batch of my kid’s favorite Honey Chipotle Chicken. Put it in containers, froze it, took it on the plane. Then, at the Airbnb, dinner was ready in 10 minutes, so we still had time to adventure on our first day! We used it in tacos, buying the tortillas, lettuce, salsa, and fruit to go with it from Walmart and Costco. 
• Breakfast burritos, individually wrapped in foil and frozen – My kid’s favorite breakfast recipe from my Cookbook. We made a double batch of these. We had some at the airport for our early flight and then some another morning. Great breakfast on the go! I used regular burrito-sized tortillas for those who could tolerate gluten and gluten-free Mission tortillas in more of a breakfast taco shape for those who needed gluten-free. Heated in the oven at 350 until warm through while we got ready for the morning. 
• Homemade S’more Cookies – I wanted to bring frozen cookie dough and cook warm fresh cookies in our airbnb, but ran out of time. So, brought some cooked ones I had already on hand. YUM. 

Packaged Snacks & Pantry Items:

We don’t have a heavy amount of prepackaged snacks in our day-to-day lives due to cost. My kids include them in their lunches during the school year and for sports on the go, but they aren’t at-home all the time snacks.

However, traveling makes me bring out all the fun snack options! Still cheaper than a $15 acai bowl…; )

• Blue Unicorn Bars – My favorite protein bar with amazing macros, is gluten AND dairy-free, and takes like a chocolate covered marshmallow. YUM. Get them here, use code WHOLEFOODFOR7 to save 10%.
• Hippea Puffs – My kids love these, especially my son who eats dairy-free. Get them on Amazon here. 
• Lovebird Protein Granola – I love love the ingredients in Lovebird cereal. And their protein granola is awesome for including protein in it as well. Get it HERE and use code WHOLEFOODFOR7 to save 15%. 
• Sprouts Items – I don’t often shop at Sprouts, but they had a great BOGO sale I used to get most of these items
  • Nuf’s snack clusters — gluten-free and a good crunchy option
  • Solely fruit snacks — just fruit, nothing else. I love the texture and flavor of these but they are a little pricey regularly. 
  • Space Balls Ranch Bites
  • Siete Queso Puffs
  • Quinn Peanut Butter Pretzels
  • Shameless Snacks – My husband doesn’t eat refined sugar, so these sugar-free candies are perfect for him. 
  • Cascadian Farm Cereals – These are fun gluten-free dairy-free cereals. We make sure to serve them with protein (dairy-free Greek yogurt) to keep them full and fueled. 
• Target Items
  • Siete Hot Honey Potato Chips — A favorite of mine for their spicy sweet combo. Not too spicy, just right! 
  • RxBars — solid protein content, great protein bar option that has Whole30 and Paleo varieties. Also sold at Costco, we just don’t love the blueberry flavor that is in the Costco box. 
  • Made Good Cheddar Star Crackers — allergy-friendly, great for kids. The closest to goldfish we’ve found in a gluten-free dairy-free variety. 
  • Gluten-free Mint Oreos – A fun travel treat that travels well. 
• Costco items:
  • Golden Island Korean BBQ Jerky Bites
  • CHOMPS Meat Sticks— a staple for every trip, gluten-free and Whole30 compatible. We rarely adventure without them! Get them cheapest at Costco, but Walmart carries them as well. 
  • Bobo’s Oatmeal Pie Bars – a great gluten-free dairy-free bar option
  • Kirkland’s Salted Mixed Nuts – a great salty crunchy option with healthy fats
  • Pure Organic Fruit Leather Bars 
• Trader Joe’s
  • Salt & Pepper potato chips – If you haven’t had salt and pepper chips, you are missing out!
  • Mini Mochi Rice Nuggets – One of my FAVORITE salty + crunchy snack options, a must-try!

Why Not Just Buy It All There?

We did buy $400 worth of groceries there from Walmart for all the other meals, including fresh fruit from Costco. (See menu below). You definitely can just buy all the things when you get there, it still saves money compared to eating out every meal. 

However, it’s not just a myth that things cost more on the islands. Here’s a direct comparison.

• The groceries I bought at Walmart in Hawaii cost $334.42.
• That *exact same* cart of groceries here in Utah cost $245.84. (see screenshot receipts below)
• = That’s a difference of 36% MORE for groceries in Hawaii. With a family of 7, that adds up fast!

Also, it’s important to note that though the Hawaii Kona Walmart had some allergen-friendly things, it didn’t have others. Like it had dairy-free mozzarella but not gluten-free pizza crusts or gluten-free Oreos. 

What Was Our Menu for the Week?

Having even a loose plan before we left made everything so much more relaxed once we got there. We knew what we had, so we weren’t guessing or stressing about meals.

HOT TIP: Use the Walmart app to order your groceries for pick up in Hawaii while at the airport on your way to Hawaii. We pulled up to the Kona Hawaii and all the shopping was done for us – saved so much time!

A meal at the airport (we ended up at Wendy’s and still paid almost $100…ouch!)

Not every meal was planned down to the detail — and that was fine. The frozen meals and snacks gave us a solid foundation, and we filled in the gaps as the week went along.

FAQ

Is it actually legal to bring food through airport security? Yes. TSA allows solid food through security. The standard 3.4 oz liquid rule applies to things like dressings and dips, but solid and frozen food is generally fine. Frozen food is especially easy because it eliminates any gray area around whether something is “liquid.”

What do you do if TSA stops you? Stay calm and be friendly. They may want to take a closer look, especially when you’ve got a cooler full of food. In my experience, they always wave me through. Organizing your cooler so items are easy to see helps a lot. Again, I have NEVER had any food taken away from me and I’ve done this dozens of times!

Can you take ice packs? Yes — as long as they’re fully frozen. Partially thawed or slushy ice packs can get flagged. Freeze them overnight so they’re solid by the time you leave and don’t pack your cooler until just before you leave for the airport. See above for link to the ones I love!

What kind of cooler bag do you use? This insulated cooler bag from Amazon — it’s the one I keep coming back to. Big enough for a family’s worth of food and works as a carry-on.

How do you keep food cold when you land? If everything is frozen, it will stay cold through the flight and the drive to your rental. We transferred everything to the fridge and freezer as soon as we arrived, but my chicken was still frozen through after a day of travel! Staying somewhere with a full kitchen (like an Airbnb) makes this much easier. 

Do you need a kitchen where you’re staying? It really helps. Even a basic kitchen setup — fridge, microwave, stovetop — means you can reheat meals without any issues. We look for vacation rentals with kitchens specifically for this reason.

What about eating out in Hawaii? There are options! Hawaii has grocery stores, Costco, and some allergy-aware restaurants. We ate out 3 times during the week. But having most of our meals already handled meant we weren’t dependent on finding the right restaurant at the right time.

Did you Eat Out at All?

Yes, 3 times. This was a senior trip for my middle son who is a foodie and really wanted to eat out EVERY meal. We comprimised and let him pick the food a few times. Please note that all of these were chosen based on HIS preferences, as well as lower-budget places. My husband is very frugal and didn’t eat a meal at these, so totals listed are for 6 people. We had:

• Nephi’s Smokehouse for lunch – Meat, rice, and veggies type place that is easy to find things that are gluten and dairy-free. I am not sure whether there is any gluten in the facility or how accommodating they would be for a celiac. But, for my DIL with dairy allergies and us with gluten sensitivities, it was great! We especially enjoyed the smokehouse fries (pictured).
  Cost for 6 = $118.07 (NOTE: they only take cash here!)

• The Coffee Shack for breakfast – I’ll be honest, we just went here because we heard you can have breakfast with the geckos. The view is amazing and sure enough, geckos crawled up eat out of jam packets. The food was mid – good but not anything amazing IMO.
  Cost for 6 = $150.06
• Kona Wave Cafe for Acai Bowls – I did a ChatGPT search for the best value acai bowls, meaning the biggest bowls for the best price. Because everything is more expensive in Kona. These were solid – not the fanciest options or toppings, but tasty. 
  Cost for 6 large bowls + 1 Smoothie = $106.51

• Wendy’s at the Sacramento Airport – We were going to buy cheaper food on the way to the airport for our travel day, as we had eaten most of the food we brought and purchased before. But, a few kiddos were running late and we didn’t have time. So, we went to the cheapest airport option = Wendy’s. Those who could eat gluten just got a burger combo, those of us who can’t had chili and fries. 
  Cost for 6 meals = $95.46

So, we spent $470 for three meals and a beach snack. OUCH. Yeah, I don’t regret bringing and making our own food at all.
