For a fizzy drink with airport food when you want to avoid the sugar in regular soft drinks, choose plain sparkling water. A no-added-sugar flavoured option may suit you if you want fruit flavour, but check its ingredients for sweeteners and acids rather than treating it as identical to plain water. If you are buying before security, check your departure airport’s liquid rules before choosing a larger bottle.
If you want fizz with a meal while cutting back on sugary drinks, plain sparkling water is a straightforward choice. The NHS also suggests diet, sugar-free and no-added-sugar drinks as swaps for sugary drinks.
A no-added-sugar flavoured sparkling water offers another option when plain water does not appeal. Check the exact bottle: Sainsbury’s mango-and-passionfruit example contains citric acid and sucralose.
Look beyond the sugar claim when choosing a fizzy drink. Northumbria Healthcare NHS Foundation Trust notes that sugar-free fizzy drinks can still be acidic and contribute to tooth erosion.
Decide whether you want plain water or flavour, then check the exact bottle and where you plan to buy it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Read the sugars figure on the nutrition panel and the product description. Distinguish plain sparkling water from a flavoured sparkling-water drink. | I want a fizzy alternative to a sugary soft drink with my airport meal. |
| Flavour and ingredients | Check whether the bottle is unflavoured or contains flavourings, sweeteners or added acids. “No added sugar” does not describe every ingredient. | Plain water does not appeal to me, but I still want to compare what is in a flavoured option. |
| Acidity | Do not use a sugar-free claim as a measure of acidity. Northumbria Healthcare NHS Foundation Trust notes that sugar-free fizz can still be acidic and contribute to tooth erosion. | Dental erosion is a concern for me, so sugar content alone will not settle the choice. |
| Security screening | Check the container size and your departure airport’s current rules. GOV.UK says containers larger than 100ml cannot pass through security at most UK airports, even when partly full. | If I want a standard-size bottle, I can check the rules before buying it or choose a drink after security. |
| Bottle and shelf choice | Compare the size and product description of the bottles available where you are shopping. Check the shelf price for the actual bottle rather than relying on supermarket comparisons. | I want a drink that suits this meal and journey, whether I prefer a single bottle or a particular flavour. |
