What is the difference between the two compartments?

One compartment opens from the top like a briefcase for quick access to a laptop or documents. The other opens front-loading like a standard suitcase for clothes and larger items.

Is it small enough to carry on?

It is sized as a 22-inch carry-on and is meant for overhead bins. When expanded it gets thicker, so check your airline's limits on smaller regional jets.

Does it have a TSA lock?

Yes. It has a built-in TSA combination lock, so security agents can open it without cutting it.

How does it compare with the Tumi Alpha 3?

Both use ballistic nylon and dual access. This large version gives more packing room and expansion, while smaller Alpha carry-ons are lighter and easier to lift into the overhead.

The exterior is ballistic nylon, with a telescopic handle, four double spinner wheels and a divider inside.

Is it good for business travel?

Yes, if you want quick access to a laptop and separate packing for clothes. It is heavier than most carry-ons, so it suits travelers who do not mind the weight.
