Are you seriously saying that you can fit everything you need to live for six whole months in a carry on less than 20 lbs? I take more than that for a one night trip.
I make it a point to keep a full wardrobe at my hub locations and a mini wardrobe at my mini hub locations.
I spent most of my entire adult working life flying.
I do not like the process of travel (checking in, waiting for you bag at your destination, humping all dat "stuff" around wit ya)
So over the years I have worked to minimize the amount of "stuff" I need to actually travel with.
And I just double (or triple up) on everything in the different locations where I spend the most time.
For the most part I only check a bag (or two) returning to the 🇩🇴 .
Most often filled with "stuff" for others.
And the occasional high priced consumer electronics for me.😉
Now, if I am traveling on vacation I pack a rolling carry on bag like everyone else. 😂
