Travellers choosing a single snack
If you want one bag for the gate, flight or onward journey, check the weight of each inner bag rather than the total weight of a multipack. The named product ranges include individual bags from 22g to 40g.
Start with the amount you want to eat: a 22g–25g bag is a smaller individual portion than a 35g–40g bag. Compare nutrition for the whole bag, then check the exact flavour’s ingredients and allergen statement if they matter to your choice. GOV.UK notes that food in hand luggage can require an additional manual security check, so keep it accessible and allow time.
If you want one bag for the gate, flight or onward journey, check the weight of each inner bag rather than the total weight of a multipack. The named product ranges include individual bags from 22g to 40g.
Pack sizes differ, so read the nutrition values for the serving you expect to eat. For example, Walkers lists 0.17g salt per 25g bag of Lightly Salted and 2.8g fat per 22g bag of Oven Baked Sea Salt.
If a vegan, vegetarian or gluten-free label matters to you, check it on the exact flavour. Read its current ingredients and precautionary allergen statement too; a plain-sounding flavour name is not a substitute.
Choose the bag size first, then compare the figures and labelling for that particular recipe. Before packing it, consider how easily you can reach it if security needs to inspect your hand luggage.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Read the weight of one inner bag and its declared serving size. Use per-bag energy alongside per-100g figures when comparing differently sized packs. | I want one bag for the journey, rather than opening a sharing pack. A 22g–25g bag is a smaller portion than a 35g–40g bag. |
| Salt and fat | Compare salt and fat on each product’s stated serving basis. Walkers lists 0.17g salt per 25g of Lightly Salted; its Oven Baked Sea Salt lists 2.8g fat per 22g. | If salt or fat is my concern, I want the figure for the bag I will eat. A claim about one Walkers recipe should not be applied to another flavour. |
| Ingredients and labels | Check the exact flavour’s ingredients, dietary claims and precautionary allergen wording on the current pack. The Food Standards Agency explains that precautionary allergen wording indicates possible unintended allergen presence. | A flavour name alone does not tell me whether the pack meets my ingredient or dietary requirements. |
| Security access | Keep hand-luggage food easy to reach. GOV.UK says food items can obstruct X-ray images and bags may need another manual check; check instructions for your airport and airline. | I would rather be able to take the bag out promptly if security asks to inspect it. |
Per-100g values help compare recipes, but they do not describe what is in differently sized bags. Walkers Oven Baked Sea Salt is listed as a 22g serving, while Tyrrells Lightly Sea Salted is listed as one 40g serving.
Check both the bag weight and the per-bag nutrition figures before deciding which portion you want.
Walkers describes its Lightly Salted recipe as having 45% less salt than the average regular potato-crisp value and its Oven Baked Sea Salt recipe as having 50% less fat than regular potato crisps. Those are different claims about different recipes and serving sizes.
Compare the nutrient that matters to you, then read the remaining nutrition panel and ingredients for the exact product.
Named plain salted products can carry precautionary allergen wording. The Food Standards Agency explains that such wording communicates possible unintended allergen presence.
Check the current pack’s ingredients and allergen statement, particularly when an allergy or intolerance affects your purchase.
GOV.UK says food in hand luggage can obstruct X-ray images and may lead to an additional manual check.
Keep the bag accessible, allow time for screening and check your airport’s and airline’s instructions before departure.
These are examples of named recipes and pack formats, not claims about every flavour in a brand’s range or what an airport shop stocks.
Its named ranges include 25g Lightly Salted bags and 22g Oven Baked Sea Salt servings.
Lightly Sea Salted is listed in 40g, 150g and 600g formats; the 40g pack is declared as one serving.
KETTLE’s named Lightly Salted recipe is a plain salted option.
The named crinkle-cut examples include a 31.8g Sea Salted bag and a 25g Canadian Ham bag.
Pipers offers a named Anglesey Sea Salt recipe alongside differently seasoned flavours.
REAL Sea Salt is listed in 35g bags sold as a case of 24.
These multipacks contain individually sized bags that you could choose for a journey. Compare the exact flavour and inner-bag size: the Hula Hoops option is a shaped potato snack rather than a conventional sliced potato crisp.

Six 25g bags provide individual portions. This is a cheese-and-onion flavour, not the plain Lightly Salted recipe; compare the salt figure on this pack rather than applying the plain recipe’s figure to it. Check its milk and precautionary allergen information if relevant.

The 22g inner bags offer a smaller portion than the 35g–40g examples in this guide. The variety pack includes Sea Salt, Cheese & Onion and Salt & Vinegar; check the nutrition and allergen details of the flavour you choose rather than applying Sea Salt’s figures to the whole pack. These baked snacks use potato flakes and starch rather than sliced potato.

Each 24g bag has a separate salt sachet, so you can decide whether to add it. That is different from buying a recipe with a stated reduced-salt comparison; check the pack’s nutrition figures and precautionary allergen wording.

The multipack contains six individual 25g bags. Walkers lists 130 kcal and 0.34g salt per 25g serving for Ready Salted. Read the current pack’s precautionary allergen statement if it affects your choice.

Six 24g bags offer individual portions if you prefer a ring-shaped potato snack. This is made with potato starch and dried potato rather than being a sliced potato crisp. It contains milk; check the current pack for its other allergen information.
GOV.UK’s hand-luggage guidance does not address crisps by name, but it says food items can obstruct X-ray images and may require another manual check. Keep the bag easy to inspect, allow time for screening and check the instructions for your airport and airline.
Use per-bag figures to understand the portion you plan to eat, and per-100g figures to compare recipes on the same weight basis. Walkers lists 96 kcal, 2.8g fat and 0.19g salt for a 22g Oven Baked Sea Salt serving; Tyrrells lists 208 kcal, 11.7g fat and 0.26g salt for a 40g Lightly Sea Salted serving. The bags are different sizes, so their per-bag figures are not a comparison of equal quantities.
No. A plain flavour name does not settle the question of allergens, and named plain salted products can carry “may contain” wording. The Food Standards Agency explains that precautionary allergen wording indicates possible unintended presence; check the current pack’s ingredients and statement for the exact recipe.
Do not assume they do. KETTLE labels its Lightly Salted recipe gluten-free and suitable for vegans and vegetarians, while Seabrook gives those labels to Sea Salted. Check the selected flavour’s current pack rather than extending either claim across a range.
