If you travel a lot I would imagine you already have TSA Pre✓ (if you qualify), or better yet you should have Global Entry for fast re-entry to the US (it includes TSA Pre✓).
With the expedited security all set for you I would then recommend a backpack to bring as carry-on that will make security carefree.
I’ve tried various brands for TSA friendly laptop backpacks, and my favorite is the SwissGear Travel Gear 1900 Scansmart TSA Friendly Laptop Backpack 19″ Blue.
Last year I flew over 130,000 miles and this backpack was there for every one of those miles. I’ve had it for nearly two years and it’s held up great.
According to the description, the backpack features “ScanSmart lay-flat technology” to open quickly at airport security and ensures a hassle-free laptop-in-bag TSA scan, but it’s been a while since they have even asked me to unzip and open it – for at least a year it’s just gone through the scanner totally zipped.
This backpack protects up to a 17″ laptop and a whole lot more.
There is an easy access laptop and iPad compartment with a front organizational pocket for all of your pens, notebook, passport, keys, etc.
Also, there is a front, large, U-zip pocket for quick access essentials. Then there are two, breathable, side compartments for an umbrella, oversize water bottle, or a change of clothes.
Before you add your things this backpack is just 3.3 pounds and very comfortable to carry.
The SwissGear Travel Gear 1900 Scansmart TSA Friendly Laptop Backpack 19 inch Blue has 4 1/2 stars out of 5 on Amazon, and I’d highly recommend it.
