Travellers counting the calories in one snack
If you want tortilla chips before boarding or during a flight, compare the labelled serving with the amount you plan to pack. A sharing bag’s per-serving figure does not describe the whole bag.
Who is this choice for?
Travellers packing food before reaching the airport
A sealed inner bag gives you a defined portion without dividing up a larger pack while travelling. GOV.UK also advises that food in hand luggage can lead to an additional manual security check.
Travellers checking ingredients and allergens
Check the current packet for the exact product and flavour. Allergen information differs between products: the Tesco listing for Doritos Lightly Salted, for example, says it is made in a factory that also handles milk, wheat, gluten, barley, soya, celery and mustard.
What should you check before buying?
Start with the portion you expect to eat, then decide whether you need a sealed bag or can measure a serving from a sharing pack.
| Priority | What to check | Your needs and survey responses |
|---|---|---|
| Serving size | Read kcal per serving and its weight. Waitrose & Partners lists 122 kcal per 25g serving for essential Waitrose Salted Tortilla Chips; Tesco lists 144 kcal per 30g displayed Chilli Heatwave inner bag in the Doritos variety multipack. Those servings are different sizes. | I want to know the calories in the amount I will actually take on the journey, rather than rely on a figure for a smaller serving. |
| Pack format | Check whether a bag is one serving or contains several. The Tesco Doritos variety listing describes each 30g inner bag as one serving; Waitrose & Partners lists eight 25g servings in its 200g essential Waitrose bag. | A sealed inner bag would save me portioning chips at the airport. If I take a sharing bag, I can measure my serving before leaving. |
| Comparable figures | Use kcal per 100g alongside kcal per serving when serving weights differ. Waitrose & Partners lists 489 kcal per 100g for its essential Waitrose chips; a smaller stated serving does not, by itself, establish a lower-calorie product. | I want to compare like with like before choosing between different pack sizes. |
| Snack type | Confirm whether the product is a tortilla chip or another crisp. Sainsbury’s lists Popchips Sea Salt potato snacks at 99 kcal per 23g serving; the 85g sharing bag contains three to four servings. | If my limit is under 100 kcal for a serving, I could consider a potato snack instead—but only if I do not specifically want tortilla chips. |
| Food labels | Read the portion, kcal and any traffic-light information shown on the pack; traffic-light colours describe particular nutrients, not the calories in the whole bag. | I want a label I can use while shopping. In a Food Standards Agency and Ipsos survey of 611 people in Northern Ireland, interviewed from 16 September to 23 November 2024, 49% said they actively used traffic-light labelling when shopping for food. That figure is not specific to airport snacks. |
| Travel and allergens | Check the current packet’s ingredients and allergen statement. Keep the snack accessible for screening: GOV.UK says food in hand luggage can obstruct X-ray images and require a manual check. | I need a snack that fits my dietary requirements and can be packed within my airline’s cabin-baggage allowance. |
What can catch you out?
-
Reading a sharing bag’s serving figure as a whole-bag figure
Waitrose & Partners lists 122 kcal per 25g serving for essential Waitrose tortilla chips, but its 200g bag contains eight servings. Eating more than 25g changes the calorie total.
Measure the amount you intend to take before travelling, or choose an individual bag if measuring a portion is impractical.
-
Assuming “popped” or “protein” means fewer calories
Waitrose & Partners lists Doritos Protein Sizzling Steak at 194 kcal for its 48g bag. A preparation or protein description cannot replace the calorie figure for the amount eaten.
Compare kcal for the intended portion and use per-100g figures when pack and serving weights differ.
-
Assuming food will pass security without a further check
GOV.UK says food in hand luggage can obstruct X-ray images, so a bag may need to be checked manually.
Allow for the possibility of screening and check your airline’s cabin-baggage limits before packing.
-
Relying on an airport shop for a particular pack
Food shopping or collection at an airport does not establish that a particular tortilla-chip flavour, pack size or nutrition label will be available there.
If the exact portion matters, buy and pack it beforehand, or confirm the specific product with the airport retailer before relying on it.
Relevant brand and product references
These examples describe particular listed products and pack formats, not every snack made or sold under each name.
Doritos
Tesco lists both Doritos sharing bags and a variety multipack with individual 30g bags.
- The displayed Chilli Heatwave inner bag in Tesco’s variety multipack is one 30g serving listed at 144 kcal.
- Tesco’s separate 180g Lightly Salted bag contains six servings and lists 146 kcal per 30g serving. These figures apply to different products and flavours.
- Waitrose & Partners lists a 48g Doritos Protein Sizzling Steak bag at 194 kcal; its protein description does not establish a lower-calorie portion.
essential Waitrose
Waitrose & Partners lists Salted Tortilla Chips in a 200g sharing bag that can be divided into portions before travel.
- The label lists 122 kcal per 25g serving and 489 kcal per 100g.
- The bag contains eight servings, so the 122 kcal figure applies only to a 25g portion.
M&S
M&S lists both Lightly Salted Tortillas and a separate popped red-lentil tortilla-style snack.
- M&S lists 481 kcal per 100g for Lightly Salted Tortillas and describes that product as gluten free.
- Its Smoked Paprika Popped Red Lentil Tortillas are a different product, listed at 439 kcal per 100g and marked unsuitable for people with a sesame or soya allergy.
Joybuy snack options
These options include tortilla chips in individual and sharing bags, followed by other sealed savoury snacks for travellers willing to choose something other than tortilla chips. Check each pack’s calorie label for the portion you plan to eat.

Doritos Chilli Heatwave 5 x 30g
Five 30g bags offer a defined pack size to take on a journey. Check this exact multipack’s calorie and allergen label before choosing it; a figure for a different Doritos multipack does not establish the calories in this product.
No image available
Doritos Tangy Cheese 180g
This 180g sharing bag suits someone prepared to measure and pack a portion before travelling. Check the Tangy Cheese label for its own serving calories and ingredients rather than using figures for another Doritos flavour.
No image available
PopChips Barbecue 5 x 17g
These individual 17g bags are a potato-snack alternative, not tortilla chips. Check this Barbecue product’s own calorie and allergen label; the serving figure for Popchips Sea Salt applies to a different flavour and pack size.
No image available
Hula Hoops Cheese & Onion 6 x 24g
The six 24g bags offer an individual-pack format if a savoury crisp matters more than having tortilla chips. This is a potato-based snack; check its calorie figure and milk and gluten information on the current pack.
No image available
Love Corn Habanero 10 x 45g
These 45g bags contain roasted corn kernels rather than tortilla chips. The product information lists 224 kcal per bag, so compare that whole-bag figure with the amount you intend to eat. Check the current pack’s warning about a facility that processes nuts and peanuts if relevant.
Frequently asked questions
Can I take tortilla chips through UK airport security?
Dry tortilla chips are not identified as a prohibited hand-luggage item in GOV.UK’s airport guidance. Food can, however, obstruct X-ray images and lead to a manual bag check; check your airline’s cabin-baggage allowance and any separate rules relevant to other food you plan to carry.
Does a 122 kcal serving mean the whole bag is low in calories?
No. Waitrose & Partners lists 122 kcal for a 25g serving of essential Waitrose Salted Tortilla Chips, while the 200g bag contains eight servings. Measure the portion you plan to pack and use the label’s 489 kcal per 100g figure when comparing products with different serving sizes.
What does a Doritos multipack change for airport travel?
An inner bag gives you a fixed pack size without dividing a sharing bag while travelling. Tesco’s Doritos variety listing identifies its displayed 30g Chilli Heatwave inner bag as one serving at 144 kcal; check the exact flavour and multipack you buy rather than applying that figure to every Doritos bag.
Is a popped or protein snack necessarily lower in calories?
No. Waitrose & Partners lists a 48g bag of Doritos Protein Sizzling Steak at 194 kcal despite its popped and protein descriptions. Compare calories for the amount you expect to eat, as well as the serving weight.
Should I check the packet again if I have an allergy?
Yes. Check the current ingredient and allergen statement for the exact flavour and pack. For example, Tesco’s Doritos Lightly Salted listing says it is made in a factory that also handles milk, wheat, gluten, barley, soya, celery and mustard; that statement should not be assumed to describe every tortilla-chip product.
