There are two kinds of business travellers at OR Tambo on a Monday morning. The first is already in an Uber, running through meeting notes. The second is standing at carousel 4, watching someone else’s tog bag go round for the third time.
For SMEs and smaller corporates, business travel has to count. A three-day trip has no slack built into it. A bag that goes missing, or time lost at the airport as you sort it out, isn’t a minor irritation. It can impact your mood – and derail your day.
“Carry-on-only used to be a personal preference,” says Herman Heunes, GM of Corporate Traveller South Africa. “Today it’s a considered decision, one that touches on cost, risk and carbon all at once.”
Here’s why carry-on-only is one of the smartest travel policies you can adopt in 2026, and exactly how to pull it off.
Why it’s worth the squeeze
Your bag is safer in your hand. SITA’s 2026 Baggage IT Insights report, released at the end of June, shows global baggage mishandling improved by 23% last year. The catch for us? Africa recorded the highest mishandling rate in the world at 12.1 bags per 1,000 passengers, around two and a half times the global average, with international routes to and from the continent averaging 15 per 1,000. On a three-day trip, day one is usually a meeting day. There’s no buffer for shopping – or a courier to deliver your suit.
It’s cheaper and getting more so. Checked baggage fees are climbing worldwide. In April, major US airlines (like United, Delta and JetBlue) all raised bag fees within a single week, largely to offset climbing jet fuel costs. Closer to home, a checked bag added at the airport on a domestic carrier can cost two to three times the pre-booked online rate.
It’s lighter on your carbon footprint. Aircraft emissions are directly tied to weight, and for passenger aircraft, approximately 50% of the weight is the plane itself, 30% is fuel, and the rest is split between passengers, baggage and belly-hold freight. Your suitcase is a tiny slice of that, but it’s the only slice you control.
It makes you disruption-proof. When a flight is grounded, everything you own is in a small wheelie bag at your side, so you can join the rebooking queue, race to a new gate or take a seat on a different plane without a second thought. The checked-bag passenger is anchored to a suitcase somewhere in the bowels of the airport or belly of the plane.
“One lost or delayed bag won’t sink a trip, but it makes everything harder than it needs to be,” says Heunes. “Packing light is a small habit with an outsized return.”
The 3-day formula
Clothing: Pick one colour “family”, for example, navy or charcoal, so every top works with every bottom. Wear your full first-day outfit and heaviest shoes on the plane, then pack two shirts, one spare pair of trousers, sleepwear and three sets of underwear. It’s a similar approach to the viral “sudoku” packing method, where you select 3 tops, 3 bottoms and 3 layering pieces. By arranging these 9 items in a 3×3 grid where every vertical and horizontal row functions as a complete outfit, you can create up to 27 distinct styling combinations. And remember, merino wool and some technical fabrics shrug off creases and resist odour naturally, allowing for multiple wears between washes.
Toiletries: Solid bars for shampoo and deodorant sidestep the liquids limit entirely (and avoid spills). Decant the rest into sub-100ml containers and let the hotel supply the basics.
Hairdryer: A hairdryer is permitted in your hand luggage, but unless you have a dinky travel-sized one, it can take up a lot of space. Another solution? Check out your hotel’s room amenity list in advance. Most will have hairdryers; if not, ask for one at reception.
Tech: One multi-plug adaptor, one cable per connector type and a power bank, which must travel in the cabin anyway. Nothing else.
Documents: Go digital. For example, Corporate Traveller’s Melon Mobile app keeps all your trip details in one place, alerts you to any flight changes or cancellations and automatically updates your itinerary accordingly. Keep your laptop, medication and valuables in your under-seat bag in case your carry-on gets checked at the front of the plane (or on the jet bridge or steps) – which can happen if the overhead bins are full.
The details that save you: Weigh your bag at home; South African carriers actively enforce the 7kg cabin limit at the gate on busy routes, and an overweight carry-on costs far more at the airport than a bag booked online. Packing cubes compress brilliantly but add nothing to your weight allowance. And if you genuinely must check a bag, book it the moment you book the flight, and drop a tracker (like an Apple AirTag) inside. Three days, one bag, zero time at the carousel. Once you’ve breezed past baggage reclaim straight into your first meeting, you won’t ever go back.
