I travel with the following.

FXT G4 22 inch wheeled non expandable.
FXT G4 Classic Garment bag
FXT G4 Expandable Computer bag.

All of my trips start out as United Express RJ flights so the two bigger ones get gate checked and I carry on my computer bag. I usually travel in F or C so I have plenty of room for my bags in the bins and keep my computer bag on the floor in front of me. You do have to be careful that you don't over fill your classic garment bag. It has lots of room and it is tempting to load it up but then it makes it hard to fit in the overhead.
