Long travel days create a lot of incidental snack waste, packaged bars, plastic-wrapped sandwiches, bags of chips at airport newsstands. Some of this is genuinely hard to avoid. Most of it is preventable with a small amount of preparation.
Pack snacks from home
The single highest-impact change. A small container of trail mix, an oat bar wrapped in beeswax, a piece of fruit. Packing two to four snacks from home covers most of a travel day and eliminates the panic-purchase moment at the airport newsstand. The savings are also real, airport snacks cost three to four times normal prices.
Bulk snacks for the bag
A handful of dried fruit, a small packet of nuts, a few crackers in a reusable container. These work as backup snacks for any travel day and don’t produce packaging when consumed. Buy in bulk before traveling; refill as needed during the trip from local supermarkets or markets.
For more on this, see our companion piece on How to Handle Trash and Recycling on Trips (When Systems Vary).
Whole foods from markets
Markets sell apples, bananas, pears, hard-boiled eggs, small pastries, dried fruits, all sold by weight or unit with little packaging. A market stop produces snacks for a day with essentially zero packaging waste. Most cities have multiple markets per week.
Avoid airport snack temptation
Airport food is the primary source of unnecessary snack waste. Eating before flying and packing snacks eliminates the urge. When you do need to buy, larger purchased items (a sandwich, a salad) usually have less packaging per calorie than small snack items.

- Oat bars in beeswax wraps
- Dried fruit and nuts
- Hard fruit (apples, pears)
- Cheese in beeswax wraps
- Whole-grain crackers
- Dark chocolate squares
- Sandwiches in reusable containers
- Boiled eggs

Long-haul flight strategies
On long flights, in-flight meals are unavoidably packaged. The choices are to accept the meal as-is, decline it (the food still gets served and discarded), or supplement with packed snacks to need less of the airline meal. Reducing total served items, where possible, is the only real lever.
What this looks like in the field
Three worked examples from recent editorial trips. These are composites built from actual editorial trips, arranged so the pattern is clear.
The plastic-free city day
A full day in a city you’ve never visited, using only your reusable bottle, reusable cup, tote, and cutlery. By evening you’ve generated essentially no single-use waste. The day didn’t feel restricted; it felt clean. You realize how unnecessary most of what you would have used was.
The week with no bottled water
Seven days in a country with safe tap water using only refillable bottles. Roughly 25 plastic bottles avoided in one week. The water tastes the same; the savings are real. The habit becomes so automatic by the end of the week that you barely notice it.
The long-haul flight done lightly
A 10-hour flight with snacks packed from home, a reusable bottle filled at the gate water station, declined cabin water bottles in favor of refills, wired earphones instead of disposable ones. The total flight waste from your seat: a small wrapper and a napkin.
What you notice after a few trips of doing this
The work of sustainable travel happens in the small interactions: the polite refusal at the corner shop, the question to the server about tap water, the choice to walk rather than taxi. Each of these is a tiny rebellion against default mode. None of them takes much effort. Together, repeated across a trip and across a year, they produce a measurable change.
The financial savings are also real. Bottled water at airports often costs $4-6 per bottle; a $25 reusable bottle pays back within a week of frequent travel. Takeaway coffee cups are charged for separately at many cafés now; a reusable cup is a quiet 10-25 cent discount each time. The math is in your favor.
The idea that outlives the packing list
Make the habits invisible to yourself. The reusable bottle lives in your day pack permanently. The reusable cup hangs from a clip on the outside. The folding tote stays in the side pocket. When the gear is just there, the habit doesn’t require a daily decision. The decision was made once; the practice continues automatically.
The last line of advice
None of this is meant to be a checklist that paralyzes the next trip you plan. It’s a set of tools you can pick from. Bring two of them. Bring five. Bring whatever feels right for the trip in front of you. Sustainable travel that gets done beats perfect sustainable travel that stays in the planning phase.

Frequently asked questions
Are snacks allowed through airport security?
Solid snacks yes. Liquids (yogurt, soups, dips) above 100ml no. Fresh fruit is generally fine at security but may be restricted at international borders.
What about meat and cheese across borders?
Many borders restrict animal products. Check the destination's rules before packing. Within the EU, generally permitted; across into Australia or NZ, generally not.
How do I keep food fresh in luggage?
Dry snacks last days. Sandwiches and fresh foods need to be eaten within hours. Beeswax wraps and silicone containers keep dry snacks fresh.
Are airline snacks recyclable?
Rarely. Airline packaging is often soft plastic that isn't accepted in most recycling streams.
What if I get hungry between meals on long flights?
Bring extra dry snacks; ask flight attendants for water and a piece of fruit. Most airlines have a small standing snack bar for the cabin.
