Travellers packing hand luggage
If you are taking biscuits through a UK airport, consider the pack size and keep the food accessible in case security asks to inspect it. GOV.UK says food can obstruct hand-luggage X-ray images.
Who is this choice for?
People comparing plain and cream-filled biscuits
If sweetness matters to your choice, compare sugars on the exact packs using the same basis, such as per biscuit or per 100g. The words “digestive” and “custard cream” do not establish a fixed nutrition profile.
Travellers checking dietary requirements
Check the packet for wheat, milk and any relevant precautionary allergen statements. Standard biscuits and explicitly labelled free-from versions can differ substantially, even within a retailer's range.
What should you check before buying?
Plain digestives
Choose when: You want a plain biscuit rather than a vanilla-filled sandwich biscuit.
Bear in mind: An ordinary digestive is not automatically gluten-free or milk-free; check the particular recipe.
Custard creams
Choose when: The cream filling is what you want from the snack.
Bear in mind: Standard and extra-cream versions have different recipes, so compare the exact packs.
Free-from digestives
Choose when: You need an explicitly labelled alternative rather than relying on the digestive name.
Bear in mind: Free-from labels address specified ingredients, not every allergy; check the full statement.
Decide on the biscuit style first, then compare the exact packet's ingredients, nutrition and size against what you need for the journey.
| Priority | What to check | Your needs |
|---|---|---|
| Biscuit style | Check whether the pack contains plain digestives or filled sandwich biscuits. Compare extra-cream variants separately from standard custard creams. | I would choose a plain biscuit if I do not want a filling; otherwise, the vanilla-flavoured cream may be the deciding feature. |
| Labelled sugars | Compare the same nutrition basis and note biscuit size. McVitie's lists 2.2g sugars per Original Digestive; Asda lists 3.4g per Custard Cream, according to their product information. | If I am comparing sweetness, I want figures for the particular biscuits I might pack, not an assumption about either category. |
| Allergens | Read the ingredient and precautionary allergen statements on the current pack. Tesco Digestives list dried skimmed milk; Sainsbury's Free From Digestives are labelled milk and gluten free but are made with oats. | For a shared travel snack, I need to know whether the exact pack meets everyone's ingredient and allergy requirements. |
| Pack format | Check the pack weight and whether you will open it before travelling. A protective food-safe container can help keep opened biscuits together. | A smaller pack may be easier for me to carry on a short trip; a larger pack makes more sense if I will use the rest. |
| Travel checks | Keep food accessible for a possible bag inspection. GOV.UK says food can obstruct X-ray images; check departure, transfer and destination requirements for your itinerary. | I want to pack biscuits without assuming that UK security guidance also settles the rules for every airport or destination on my route. |
What is easy to overlook?
-
Assuming “digestive” means free-from or nutritionally lighter
The name does not establish an allergen status or a particular nutrition profile. Tesco Digestives, for example, list dried skimmed milk.
Use the current ingredients, allergen statement and nutrition table for the exact product you intend to buy.
-
Comparing all custard creams as one recipe
M&S describes its Extra Cream Custard Creams as containing more vanilla cream than its standard version. That positioning does not describe every custard cream.
When switching between standard and extra-cream biscuits, compare their labels on the same per-biscuit or per-100g basis.
-
Assuming packed food needs no further travel checks
GOV.UK says food can obstruct hand-luggage X-ray images. UK departure guidance also does not determine what a destination permits you to bring in.
Check your departure and transfer airports, airline and destination before travelling, and keep biscuits separate from liquid or semi-liquid foods such as jam or honey.
-
Using an online allergen listing instead of the packet
The packet is the label you will have with you when serving or sharing the biscuits, including any precautionary allergen wording.
Read it before travel, particularly when buying for someone who must avoid wheat, milk or another ingredient.
Relevant brand and retailer ranges
These examples illustrate differences between specific biscuit lines; they do not describe every product sold under each name.
McVitie's
Its Original Digestives are a plain-biscuit reference for shoppers comparing labelled nutrition.
- McVitie's lists 2.2g sugars per Original Digestive.
- The recipe contains wheat, and the product may contain milk; check the packet for your requirements.
Tesco
Tesco lists both standard Digestives and vanilla-filled Custard Creams, allowing a comparison between its two biscuit styles.
- Tesco Digestives list 2.1g sugars per biscuit.
- Its Digestives list dried skimmed milk; check the Custard Creams' separate ingredient statement rather than treating the products alike.
Sainsbury's
Its standard and Free From Digestives serve different ingredient requirements.
- Sainsbury's labels its standard Digestives suitable for vegans and its separate Free From Digestives milk and gluten free.
- The Free From product is made with oats; check its full allergen statement, including precautionary warnings.
Asda
Asda Custard Creams are a standard vanilla-filled sandwich-biscuit example.
- Asda lists 3.4g sugars per biscuit.
- The product contains wheat and milk.
M&S
M&S positions its Extra Cream Custard Creams as a distinct, more heavily filled variant.
- M&S describes the biscuits as containing more vanilla cream and real custard powder.
- Check this variant's own ingredients and nutrition rather than applying standard custard-cream figures to it.
Crawford's
Crawford's Custard Creams offer the traditional vanilla-flavoured sandwich-biscuit format.
- The product listing describes a vanilla-flavoured cream filling and labels the biscuits suitable for vegetarians.
- Check the pack's wheat and milk ingredients if buying for someone with an allergy.

Questions about biscuits and airport travel
Can I take digestives or custard creams through UK airport security?
Dry biscuits are not among GOV.UK's examples of liquid or semi-liquid foods, but do not treat that distinction as a guarantee of clearance. GOV.UK says food can obstruct hand-luggage X-ray images, so keep the pack accessible if security needs to inspect it.
Will the same food rules apply on my return journey?
Do not assume UK departure guidance covers your whole itinerary. Check the rules for your departure and transfer airports, airline and destination, including any restrictions on bringing food into the destination country.
Are ordinary custard creams gluten-free or milk-free?
Do not assume they are: the cited Asda Custard Creams contain wheat and milk. If either ingredient matters to you, choose a product with the appropriate explicit labelling and read its current packet for other allergens.
Is every digestive suitable for vegans?
No. Sainsbury's labels its standard Digestives suitable for vegans, whereas Tesco Digestives list dried skimmed milk. Check the suitability statement and ingredients for the exact pack.
How should I pack biscuits in hand luggage?
Keep them in their pack or a protective food-safe container, and place them where you can reach them if asked to present food at security. This is a practical packing step, not a guarantee that a bag will avoid inspection.
