Which carry-on bag for a one-week trip?

Traveling for a week with a carry-on bag is possible provided you choose it carefully. You need a bag that is spacious enough to hold your essentials, yet compact enough to pass as carry-on without extra charges. The ideal size ranges from 40×30×20 cm to 55×35×25 cm, with clever storage and good internal organization. A compressible backpack will allow you to optimize every centimeter.

FAQ on carry-on bags for a week of travel

What capacity do I need for a week?

Between 30 and 40 L is sufficient if you optimize space (rolling clothes, compact toiletry bag, nothing unnecessary).

Should I use a backpack or a carry-on suitcase?

A soft carry-on bag is more practical if you are traveling with a low-cost airline. It fits under the seat and avoids extra fees.

Can I pack shoes in a carry-on bag?

Yes, if the bag has a bottom or side compartment. Otherwise, wear the bulkiest pair and pack one pair in the bag.

Is a compressible backpack enough for a week?

Yes. Compression models allow you to fit the equivalent of a suitcase into a carry-on format.
