If protein is the reason for choosing crisps for an airport journey, compare the amount in the bag you will carry: Applied Nutrition declares 15g per 50g bag and Myprotein declares 11g per 25g bag, while the checked conventional potato crisps contain less than 2g per bag. Check salt and allergens on the exact flavour before buying, and keep food accessible in hand luggage in case security needs to inspect it.
If you want a savoury snack for the journey, compare individual packs rather than assuming all crisp-style products provide similar amounts. Applied Nutrition, Myprotein and EatProtein declare 11–15g protein for their listed bags or ranges.
Protein is only one part of the choice. Read the exact flavour’s ingredients and allergen declaration alongside its nutrition panel, particularly if you avoid soya or other specified ingredients.
A sealed snack is easy to put in a cabin bag, but GOV.UK warns that food can obstruct security X-ray images and lead to a manual bag check. Check your airline’s cabin-bag allowance as well.
Start with protein per pack, then compare the rest of the label and the practicalities of carrying that particular pack. In a 2024 Northern Ireland survey of 611 respondents by the Food Standards Agency and Ipsos Northern Ireland, 49% said they actively used traffic-light labelling while shopping for food; that figure does not measure demand for protein crisps or airport snacks.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per pack | Compare grams per bag and the stated bag size, not just values per 100g. Applied Nutrition declares 15g per 50g bag; Myprotein declares 11g per 25g bag. | I want to know how much protein is in the pack I will actually take, rather than judging by a product name. |
| Whole nutrition label | Read salt and energy per bag alongside protein. Myprotein’s checked 25g Salt & Vinegar bag lists 1.40g salt. | I want the full figures for my chosen flavour. The Food Standards Agency and Ipsos Northern Ireland found that 49% of their 611 Northern Ireland respondents actively used traffic-light labelling when shopping for food in their 2024 survey; this was about food shopping generally, not protein crisps. |
| Ingredients | Check the protein source, declared allergens and any “may contain” wording on the exact pack. Do not assume different flavours have identical ingredients. | If I avoid a particular ingredient, I need to check the pack I am buying rather than rely on the range name. |
| Travel packing | Check the pack format and your airline’s cabin-bag allowance. GOV.UK says food in hand luggage can obstruct X-ray images and prompt a manual check. | I want a snack I can reach easily if security asks to inspect my bag. |
The amounts differ substantially between the checked packs: Walkers lists 1.5g per 25g Pickled Onion pack, Seabrook lists 1.9g per 31.8g Sea Salted bag, and Tyrrells lists 3.9g per 30g serving of Lentil Crisps.
Compare protein on the same serving basis you plan to eat. For a UK “high protein” claim, the condition stated in the legislation published by legislation.gov.uk is that at least 20% of the food’s energy value comes from protein; an ingredient or product name alone does not establish that.
A protein figure cannot tell you the pack’s salt content or whether its ingredients suit you. Myprotein lists 11g protein and 1.40g salt per checked 25g Salt & Vinegar bag.
Read the current nutrition panel and allergen declaration for the flavour you intend to carry.
GOV.UK warns that food can obstruct hand-luggage X-ray images, so security staff may need to check a bag manually.
Keep the snack accessible, allow time for a possible check and confirm your cabin-bag allowance with the airline.
These published product figures help distinguish protein-focused snacks from conventional crisps; they do not indicate which brands a particular airport shop carries.
Its Protein Chips are a protein-focused crisp-style option sold in a listed 50g bag.
Its checked Popped Protein Crisps provide a smaller individual pack for a per-bag comparison.
Its protein-crisp range offers another crisp-style option to compare by individual bag.
Its Lentil Crisps offer a lentil-based comparison if that style appeals more than a protein-focused crisp.
Its Sea Salted potato crisps provide a conventional-crisp comparison point.
These options cover a lentil cake for someone seeking a crisp-style snack and a peanut-and-chocolate bar for someone open to a different texture. Compare their pack formats with the individual protein-crisp bags discussed above.

A lentil-cake option if you want a crisp-style snack for the journey. It comes in a 100g pack rather than the individual bags used in the protein-crisp comparison, so check the label for the amount in the portion you plan to carry and for allergen information.

A bar rather than a savoury, crisp-style snack, so it suits a different texture preference. The listed pack contains four 40g bars; check the current pack for protein per bar and its allergen declaration before choosing it for travel.
Read protein per bag and the full nutrition panel, rather than relying on the product name. The UK high-protein claim condition published by legislation.gov.uk requires at least 20% of a food’s energy value to come from protein; grams of protein alone do not establish whether a particular product meets that condition.
Packaged crisps can be carried for screening, but do not assume your bag will pass without a check. GOV.UK says food can obstruct X-ray images and may prompt manual inspection; keep the pack accessible and check your airline’s cabin-bag allowance.
No single range name establishes suitability for every flavour or dietary requirement. Check the current ingredient list, allergen declaration and any “may contain” statement on the exact pack you intend to buy.
Check the snack’s ingredients, where you are travelling from and the current GOV.UK rules for bringing food into Great Britain before your return journey. The government’s overview says rules apply to food and animal products brought in for personal use; it does not establish one rule for every crisp product.
