I travel for work, and this simple packing habit makes flight disruptions less stressful

When I check a bag for a flight, I never assume I’ll have immediate access to everything inside it when I arrive. And I almost always check a bag, because my personal item already holds camera gear and a laptop, and I’d rather not haul a heavy suitcase through airports on top of that.

But that doesn’t mean I pack half my suitcase into my carry-on. I just make sure I have enough with me to get through one unexpected night and the following day.

It’s a habit that started when I traveled frequently for business. If I had a meeting the morning after an international flight, arriving without my checked suitcase could create a real problem. So my carry-on always included a work-appropriate outfit, underwear, makeup, medications, and basic toiletries.

When I traveled with colleagues, I encouraged them to do the same. None of us wanted a delayed suitcase to be the reason we showed up to a presentation in the yoga pants and sneakers we’d worn on the plane.

I prioritize essentials for where I’m going

My travel has changed, but I still follow the same rule.

These days, I often travel between places with completely different weather. I may leave home wearing a winter coat and arrive somewhere warm enough for sandals.

So if I’m heading to an island or another warm-weather destination in winter, I’ll pack a lightweight dress and sandals in my carry-on. I’ll sometimes add a swimsuit, too, since finding one that fits well can be harder than replacing basic clothes.

Why I pack the same way for the flight home

I usually repeat this on the return trip, too. It can be tempting to squish everything back into your checked suitcase once the vacation is over, but delays and missed connections can happen just as easily on the way home.

On a recent trip home from Central Asia, I had a layover in Europe and missed my connection. I was already well into an itinerary that involved more than 20 hours of travel, so an unexpected hotel night was the last thing I wanted.

My checked suitcase stayed behind, but I had a change of clothes, makeup, medications, and a few basic toiletries in my carry-on. It didn’t fix the missed flight, but having those essentials with me made a long, tiring trip considerably easier.

What else should stay in your carry-on?

Along with a complete change of clothes, keep anything you’d have trouble replacing during the first day or two of a trip in your carry-on. That includes prescription medications, essential toiletries that meet TSA liquid limits, glasses or contact lenses, and any important travel documents.

Everyone should also keep a phone charging cable and wall plug in their carry-on so they can recharge during delays, long layovers, or an unexpected overnight stay. A portable power bank can be useful, too, and lithium-ion power banks must travel in carry-on baggage rather than checked luggage.

The question I ask is simple: If I didn’t see my checked bag again until tomorrow, what would I wish I had with me?

A small backup plan can reduce a lot of stress

Most of the time, my checked bag arrives when I do and the extra clothes stay folded in my carry-on, which is fine. I don’t pack them because I expect something to go wrong.

I pack them because missed connections, delayed bags, and unexpected overnight stays are much easier to handle when I already have the basics covered.

For me, one destination-appropriate change of clothes is a small amount of extra planning for a lot of peace of mind.
