Flying to a trek: carry on, check or buy there

This guide covers four trips: Kathmandu and Lukla for Everest, Cusco for the Inca Trail, Moshi or Arusha for Kilimanjaro, and Puerto Natales or El Chaltén for Patagonia. Each starts with a long flight under the dangerous-goods table that IATA publishes for airlines, and the Everest trip adds a short hop on a small plane with its own weight limit. Rows marked US apply at American checkpoints, where every TSA item page says the officer has the final decision.

Power banks get one row here. The electronics guide has the watt-hour limits, the per-person counts and the airlines that ban using a bank in flight. Layering for cold lodge nights sits in the cold-weather guide, and boot choice, along with New Zealand's NZ$400 instant fine for undeclared dirty boots, in the shoes guide.

Twelve trek items under three rulebooks

Every source in this table was read on 8 Oct 2026. The trek-country column quotes airlines, an airport and parks in the trek countries: Tara Air and Nepal Airlines in Nepal, Lima Airport in Peru, the Tanzanian airline Flightlink, and the park rules at Machu Picchu and Los Glaciares. The IATA column is the 67th edition of its Dangerous Goods Regulations, dated 1 January 2026, and IATA publishes a new edition every year (IATA DGR), so check the table again for flights from 1 January 2027.

Two rows split the US from the rest: poles with crampons, and headlamp batteries. TSA lets crampons and blunt poles into the cabin, while Lima Airport keeps ice picks out of the cabin and passes walking sticks only once they have been shown to the security officer. US screening isn't predictable either. On r/hiking, Expensive_Profit_106 called carrying poles on "a gamble" that "could be the last time you ever see those poles", and Jasper2006 described five or six cabin trips before "one time TSA said "NO!"" and a gate agent taped and checked the pair.

Headlamp batteries are the row where the flight home from Kathmandu is stricter than the flight out of the US. The TSA allows alkaline AA and AAA cells in a checked bag, though spare lithium AA and AAA cells are cabin-only there too. IATA's table keeps every spare battery, dry cells included, in carry-on baggage, and Nepal Airlines prints the same line. Pack to the stricter rule for the whole trip and tape the terminals.

Neither the FAA nor IATA makes an exception for gas. The FAA's fuels page covers "compressed fuel canisters, liquid fuels, and solid fuel tabs". IATA's table opens by saying dangerous goods "must not be carried" except as it lists, and gas cartridges for stoves aren't on that list. The only canister at camp is one bought in the trailhead town. A used fuel bottle is a closer call: IATA permits an emptied one as checked baggage, and only with the airline's approval, and the FAA notes airlines that turn down used camping equipment "regardless of how well it has been purged".

The Lukla flight's 15 kg, and who publishes it

Tara Air prints its limit in its terms: "Free baggage allowance limit (10 kg baggage + 05 kg hand carry)", 7 kg for a child, and "Excess baggage fees apply" beyond it. Its FAQ repeats the 10 kg checked and 5 kg of hand luggage and lists Kathmandu, Ramechhap and Lukla among its destinations. The 15 kg is official, then, but it's the airline's figure. Tara Air's terms also say to keep "computers, personal electronic devices" and money out of checked baggage.

We didn't find a baggage figure from the regulator. The Civil Aviation Authority of Nepal (CAAN) posts dangerous-goods regulations and manuals for airlines and handlers, and its 2073 BS air-fare directive (CAAN library) sets rules for fares, cancellations and charters with no baggage weight. Its flight-safety site returned errors on 8 Oct 2026. Summit Air and Sita Air also fly to Lukla (Republica), and neither prints a number. Summit Air's policies page bars compressed gas and lighter fuel without its consent and doesn't give a free allowance, and Sita Air's terms mention weight limits without a figure. If the ticket is on one of them, the number to plan around is the one printed on that ticket.

If the checked bag doesn't arrive

A lost bag on the way to a climb is a real failure mode. On r/kilimanjaro, 00rvr wrote "Someone in my group had to rent and buy everything because her airline lost her luggage". The fix is to fly in carrying what's hardest to replace and what day one needs. Tanzania National Parks lists the core of it in its Kilimanjaro visitor guide: "Carry proper cold-weather and rain gear, headlamp, and personal meds."

Boots come first. In another r/kilimanjaro thread, SiddharthaVicious1 explained that "your boots are the hardest thing to rent or replace because you have already broken them in." An operator in the same thread, AltezzaTravel, advised the opposite: "I recommend keeping your boots/clothes in your checked luggage." We'd still wear them. Even a commenter who rented almost everything brought boots from home: on the r/kilimanjaro rental thread, northern_peony listed the rentals but said "I would definitely bring your own boots and base layers."

Then the cabin bag. Medication goes there, and the medication guide covers prescriptions and liquid medicine. So do documents, the power bank and spare batteries that have to ride there anyway, the rain shell and one warm layer. The water filter joins them because Sawyer tells its own customers to fly with it in the carry-on "so it stays protected from compromising conditions below the cabin." The rule of thumb from ClimbKiliTeam, a Kilimanjaro climbing account, is the test for anything else: "packing what can get you started on day one of the mountain". Poles, stakes, a knife and spare clothes stay in the hold. Poles are for rent at all four hubs below, and the rest matters less on day one. The printable checklist has a cabin-bag group for ticking these off the night before.

Buying or renting at the trailhead towns

In Kathmandu, Thamel is where the rental shops cluster. bikal_TripPlanner on r/Nepal listed what to rent rather than buy: "down jacket and sleeping bag, both bulky and expensive and youll likely never use them again", along with a porter's duffel and trekking poles, and added "thamel has loads of rental shops". The same comment asks you to check the bag's rating ("you want comfort around -10 to -15, gorak shep nights are cold even in spring") and to keep the passport itself back from the deposit: "dont hand over your actual passport".

Kilimanjaro works differently, because nobody climbs alone. Tanzania National Parks states "All climbs must be guided by a licensed operator; solo trekking is not permitted", the tented camps are run by licensed operators, and open fires are restricted, so stove and gas belong to the crew. Rental runs through the operator or local shops. AltezzaTravel, an operator, warned on r/kilimanjaro that local shops stock used gear from guides and porters, and suggested asking your operator for photos and model names before you pay.

The Inca Trail runs through agencies too. Peru's culture ministry resolution RM 333-2026-MC has registered Cusco agencies buying trail tickets for their clients through its TuBoleto platform, and the trip price can include the kit. A March 2026 trip report on r/Machupicchu listed "hire of all equipment (sleeping bag, the sleeping liner and walking sticks)" in the price and said "Make sure you get walking sticks". Hired poles stop at the citadel gate, because Machu Picchu's rules bar walking sticks (bastones) and bags over 40 × 35 × 20 cm.

Patagonia is where you cook for yourself, and where gas is easiest to find. On r/Patagonia, SteelCurtain1933 wrote "These gas cartridges are pretty common in PN as there are a lot international tourists", and for the W trek Apprehensive_Arm1881 promised "There will be plenty of leftovers at each campsite kitchen, plenty!" In El Chaltén, a January 2026 reply on r/ElChalten found isobutane at a second outdoor shop after the first had none: "They had a large bin full of them." Park rules limit where the stove burns. Torres del Paine's regulation allows fire only through portable stoves at expressly authorised sites. Argentina's park service allows only gas stoves at designated campsites in the northern zone of Los Glaciares and warns that the trails have no supplies. Gear rental exists in El Chaltén too ("You can rent gear easily in El Chaltén and prices are very reasonable", flying-pineapple27 wrote on r/backpacking), though that report dates from 2023.
