Both, i travel lots for work and leisure and use both.

i am a my servsnts will look after my baggage sort of person...

Backpack

I have a Augur canvas one. It fits quite a bit.

I like stuff with wheels

Swiss Army backpack. Had it for 11 years.

A luggage and a handcarry. True story.😂

I'm a luggage kind of guy. Actually I have a big duffle bag that I use.

Backpack. I never had a proper suitcase.

When I travel I use a small duffle-type bag and a small inexpensive backpack for carrying 'stuff" when I'm out and about. I quit real luggage about 30 years ago... I'm a guy, so I don't take much.

I don't travel, but if I did, I'd wanna pay extra for someone to carry it all for me!!

I have a travel backpack for my trips that doubles as a carry on.

Plus a roller bag for my snacks.

I travel light as possible I hate carrying anything, but if a have to, backpack or a small suitcase.

Luggage.
Do backpackers have any idea how annoying those things are to fellow travellers in confined places like busy train platforms or escalators ?

I like hands free. I use a backpack instead of a purse too. I'm that nerd with a backpack and and a fanny pack 😂

My back packing days are over,done kaputnick..but I do carry a lot of baggage

I always travel with my Northface or Osprey Backpack, plus my carry on.
If I’m going away for a month, I would check in a medium size luggage.

I travel light and tend to use a duffle bag.

Luggage

I dont bring more than i can carry on my back. I have a hiking backpack that i use for everything.

Luggage person

I usually have a day pack shoved under the seat in front of me, and a two-wheel rolling bag in the overhead bin. BTW, European overhead bins have slightly smaller size constraints than the ones in the US.

I'm a duffle or luggage traveler unless overnight hiking

Im a backpack person for sure. Luggage is so annoying

Overhead bin roll on and an underseat bag

Luggage (checked in) and then a small bag in the plane. I feel naked without some of my stuff so the bigger the better.

All depends on the holiday

A rucksack or a fabric luggage-bag. I don't own any suitcases.

Backpack and maybe a duffle bag

I carry nothing but the clothes Im wearing and a wallet like Jack Reacher.

I think both. It depends

Luggage, mostly.
I'm diabetic and have to bring my stuff with me so, I'll pack that in a smaller travel bag.

Not a backpack type of gal, sissy. lol
Luggage only, just got back from a trip to the midwest.

I have a carry on that’s both on wheels and turns in to a backpack. I look like a major dork but I do not care. I’m ready for all scenarios.

Before getting the motorhome I mainly used a backpack.

Back pack

Back pack light as possible.

It depends on the mission

cardboard box or garbage bag .
