Don't touch the passport. Just get a leather cover for it that has pockets. When ever you go through customs just take it out. It's all of a 2 second ordeal.

If you don't have a case the cover tends to start trying to tear which makes the passport invalid. I've had my holder for 16 years and it's still in good condition. My monogram name is the only thing starting to wear but that's not a big deal.

Just bring an extra shirt or two depending on the trip length and set of overnight street clothes. I normally pack two pilot shirts, two undershirts, a pair of jeans, two button down shirts, socks for every day and underwear for everyday. If it's winter I have a light shell jacket that go in for the overnights.

I typically only pack 3oz bottles of toiletries. As it makes dealing with the TSA easier if I decide to go sans monkey suit for my commute.

I have a small cooler that snaps onto my bag. I put some microwave soups and snacks in the main cooler. Some overnight hotels don't have food in or nearby, especially small BFE airports. Since this bag fits beside my seat I put anything personal I might need it its upper compartment. Like my ear plugs, TOLD cards, gum, extra pens, etc...

Last but not least I have a brightline flight bag for my headset and EFB. I also have my portable GPS/ADSB puck incase the weather is ****. But you didn't hear me say that.....

I could easily get rid of the flight bag if I chose to use the company headsets. Hope this helps!

Hotel laundry bags make great receptacles for dirty clothes. I usually take one from my first overnight on a trip, and keep adding dirties to it until I get home. Get a multi USB charger for your electronics, and carry one unit all your cables plug into. Anker makes some great ones. Also, do the forget a good backup battery, Anker also makes some good ones.

For a REALLY light packer;

FlightCrew 5 19" Slim Rollaboard

Aurora 17" Rolling bag - New Series

Most hotels provide plastic laundry bags

Do most regional airlines not provide luggage?

If you coming to Republic, we get flight works for free at Indoc. They don't ship them though until after you pass your ride though.

or just an industrial size bottle of Hai Karate.

No sir....

Buy your toothpaste in the half sized shampoo bottle. Small tubes are annoying and large ones can get pulled if you forget and commute in a polo one day.

Put everything in the same compartment every time.

When you unplug any thing charging, unplug from the wall not the device.

Leave a compartment open if it's items aren't in it. When you go to close you will remember why it was open to begin with.

Use the hotel hair conditioner as shaving cream.

Pack the same clothes every time. Suitcase, washer, dryer, suitcase. Buy two of everything you need so your suitcase has a dedicated toothbrush, razor, charger, etc..

Don't set your flashlight or sunglasses down in the plane, in your hand or in your bag. You will get up during an aircraft swap and leave them.

Pack a polo for your commute home so you can drink in first class.

Pretty sure I would not be able to handle toothpaste that tastes like shampoo. Maybe that's just me.

Not sure about the unplug from the wall advice? My charger goes in a pocket, as well as the cables. The devices I use. Wouldn't want cords dangling from them as I use them.

It's regular tooth paste, just sold in a vertical bottle the size of a stick of deodorant, and doesn't have a screw top, it has a flip top like hair shampoo.
TSA doesn't flag those.

The wall issue is it forces you to pack it. If you unplug from the device you will be in the airport van remembering you left your charger plugged into the wall behind the night stand.
