Carry-On Business Trip: A 5-Day Practical Check with a Suit and Laptop

Before packing, everything gets laid out on the bed: laptop, charger, mouse, suit, two shirts, one tie, three pairs of underwear, three pairs of socks, a t-shirt for evenings, toothbrush, deodorant, razor, those tiny 100 ml bottles for shampoo and shower gel.

Then it's onto the scale. And the stomach drops.

The laptop alone: 1.8 kg. The suit with trousers: roughly 1.4 kg. That's 3.2 kg before a single wearable item. Lufthansa allows a maximum of 55 x 40 x 23 cm and 8 kg. Sounds generous. Until the laptop and suit hit the scale.

The plan: laptop and charger go into the Laptop Rucksack Herren Business Rucksack leicht 15.6 Zoll wasserdichter erweiterbarer Reiserucksack as a personal item. Suit, shirts, and everything else into the trolley. Two bags, both permitted on Lufthansa Economy — a system that holds up for the whole trip.

This is the part that gets dreaded most. A suit inside a carry-on trolley sounds like a recipe for wrinkles.

A tip from Carryology: slip a thin dry-cleaning bag between the jacket and trousers. The plastic reduces friction, which reduces creasing. Sounds odd, but it genuinely works. At least for the first two days.

By day three, the jacket often looks like someone slept in it. After two days folded in a trolley, that's not far off.

So: bathroom, hot water on full, door shut, steam it up. Jacket hanging, 15 minutes waiting, gentle smoothing. Around 80% of the wrinkles disappear this way.

What's worth changing for next time: bring a Travando Anzugtasche mit 15" Laptopfach und Schultergurt - Kleidersack Anzug Tragetasche instead. It counts as a personal item on most airlines and keeps the suit in much better shape. For business travelers who regularly fly carry-on only, it's the obvious move.

Compression packing cubes save the whole thing. Sounds excessive? It is, a little. But without the Koffer Organizer Packing Cubes Compression 8 Stück, Wasserdicht Packwürfel Koffertaschen, the suitcase simply doesn't close.

A carry-on business trip packing list for 5 days:

• 1 suit (jacket + trousers)

• 2 dress shirts

• 1 tie

• 3 underwear, 3 pairs of socks

• 1 t-shirt, 1 pair of joggers for hotel evenings

• Toiletry bag with 100 ml bottles

On travel day, wearing the heavy shoes and carrying the jacket over the arm saves 1.5 kg of suitcase weight — and only costs one slightly odd train ride to the airport.

For the trolley itself, the Amazon Basics Hartschalen-Kabinen-Koffer - ABS-Handgepäck Zugelassen für Ryanair - 55 x 40 x 20cm is a solid pick. Ryanair-approved, 55 x 40 x 20 cm, under 3 kg empty. Not the fanciest suitcase in the world, but it fits every gate sizer — for under 50 euros, a fair deal.

With more budget: the Samsonite S'Cure - Spinner S Handgepäck, 55 cm, 34 L, Schwarz weighs about the same, rolls better, and looks more professional at the gate. For regular carry-on business travelers, probably the smarter investment.

Works:

• Laptop in the backpack, clothes in the trolley. Two bags, zero stress at the gate.

• The bathroom steam trick. Saves packing a travel iron.

• Hanging shirts up each evening. Simple, but it makes a real difference.

• Wearing the heavy items on travel day.

Doesn't work:

Shirt number two on day four. Usually not presentable anymore. Washing it in the sink, spreading it over the radiator, and hoping for the best is the only real option. At 7 in the morning it's often still slightly damp – it goes on anyway.

The toiletry bag. Fills up fast. Security in Munich wants everything out individually then — four trays later, half the queue is waiting.

The evening outfit. T-shirt and joggers are practical, until a spontaneous invitation for a beer on Thursday evening shows up with nothing else to wear.

Days four and five cost some comfort. Not much — but enough to know: at five days, the carry-on business trip is doable but not a relaxed experience anymore. It's a compromise — one worth making, but not without a third shirt.

One thing that's easy to miss: suitcase depth. The obvious move is often to just bring the trolley that's already at home. 55 x 40 x 23 cm. Fits Lufthansa, fits Eurowings.

Does not fit Ryanair.

Ryanair allows only 20 cm depth. Three centimeters less. Sounds like nothing. But most standard trolleys won't pass Ryanair's gate sizer. And Ryanair now pays staff 1.50 euros per oversized bag they catch. Gate fees run up to 80 euros — which is exactly why travelers can be seen frantically repacking their suitcase right at the gate sizer.

We've put together a full breakdown of oversized baggage fees across all major airlines — from Ryanair to Eurowings. And in our test of carry-on suitcases 55x40x20 approved by Ryanair and Lufthansa, we ran seven models through the gate sizer.

Anyone switching between airlines needs a suitcase that fits the strictest carrier. Not the most generous one.

Can you do a 5-day carry-on business trip? Yes. Barely.

For two or three days? Absolutely, and it's an easy recommendation. If you want to ease into the concept first, this experience report: carry-on only through Europe is a good starting point for shorter trips. According to the SITA Baggage Report 2024, millions of bags are mishandled or damaged by European airlines every year. If you need your suit for an important meeting, that's not a risk worth taking.

But five days? It gets tight. It's doable regardless: no checked luggage, no waiting at the carousel, no check-in stress — and roughly 30 minutes saved per flight.

For next time, a third shirt is worth packing. No maybe, no "we'll see" — just a third shirt. A second trolley still isn't worth bringing along: the 30 minutes saved at the carousel and the zero risk of a suit landing in a different city outweigh one half-damp evening shirt easily.
