Travellers packing hand luggage
If you want separate servings for different stages of a trip, check how many bars are individually wrapped and keep them accessible. GOV.UK says food can obstruct X-ray images, so a bag may need another check.
Who is choosing these bars?
Travellers comparing nutrition per bar
A smaller oat bar and a larger protein flapjack are not equivalent portions. Compare serving weight alongside energy, sugars, protein and fibre on the exact product label.
Travellers with dietary or allergen requirements
Choose against the current pack’s ingredients and allergen statements. A vegan or gluten-free description does not establish that a bar is free from nuts, wheat, soya or milk.
What should you check?
Start with the number of usable servings, then compare nutrition and ingredients for the particular bars you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Portions and packing | Count the bars and check whether each is wrapped separately. Keep food accessible in case security needs to examine the bag; GOV.UK says food can obstruct X-ray images. | I want to take only the servings I expect to use and find them easily if my bag needs checking. |
| Protein and fibre | Read the amounts per bar and its serving weight, not just the claim on the front. A 30g serving and a 50g serving represent different portions. | If protein or fibre is my priority, I want to know what one bar provides rather than judge it by its product name. |
| Sugars and energy | Compare total sugars and energy per bar, alongside serving weight. Tesco lists 15g sugars in a 35g nākd. Cocoa Delight bar despite its no-added-sugar label. | A no-added-sugar claim is useful to me only alongside the total-sugars figure for the portion I will eat. |
| Ingredients and allergens | Read the exact flavour’s ingredients, highlighted allergens and any “may contain” statement. The Food Standards Agency explains that precautionary wording signals possible unintended allergen presence. | I need to check the particular pack against my dietary requirements; a brand-wide description or vegan label is not enough. |
What is easy to overlook?
-
Judging the whole bar by one nutrition claim
“No added sugar” does not describe total sugars: Tesco lists 15g per 35g bar for nākd. Cocoa Delight.
Check the serving weight and full nutrition panel when comparing protein, fibre, sugars and energy.
-
Using vegan or gluten-free as an allergen check
The Joybuy listing for TREK Biscoff Protein Flapjack identifies wheat and soya and warns of possible peanuts, nuts and milk. Tesco’s nākd. Cocoa Delight listing also carries allergen warnings.
For an allergy, read the current pack’s ingredients and precautionary statements for the exact flavour.
-
Burying the snacks at the bottom of a bag
GOV.UK says food may obstruct an X-ray image and lead to an additional manual check.
Pack bars where you can reach them, and check the guidance for your departure airport, airline and any transfer.
-
Assuming a multipack contains separate servings
A pack’s total weight does not tell you how conveniently its contents can be divided across the journey. Tesco specifically describes the Eat Natural 3 x 40g pack as individually wrapped.
Check the wrapping and number of bars on the exact pack before deciding how many portions to take.

Questions about airport snack bars
Can I pack snack bars in hand luggage for a UK airport departure?
GOV.UK’s hand-luggage guidance does not list ordinary snack bars as a prohibited category, but says food can obstruct X-ray images and lead to an additional manual check. Keep bars accessible and check your departure airport, airline and any transfer-airport guidance before travelling.
Does “no added sugar” mean a bar has little sugar?
No. Tesco lists 15g total sugars per 35g bar for nākd. Cocoa Delight, which is labelled no added sugar. Read the total-sugars figure and serving size on the exact pack.
What should I check if I have a food allergy?
Read the ingredients, highlighted allergens and any precautionary wording on the current pack of the exact flavour. The Food Standards Agency explains that a “may contain” statement communicates possible unintended allergen presence; vegan or gluten-free labelling does not replace that check.
Which of these bar ranges have vegan options?
Tesco labels Graze Cocoa Vanilla Oat Boosts suitable for vegans, while TREK describes its bars as plant-based and nākd. describes its fruit-and-nut bars as vegan. Check the exact current product label, particularly if you also need to avoid an allergen.
