I've switched to carry-on only. I use the Osprey Porter 46

Great size can use it for any trip (but too much for shorter 2-4 day trips). I often do trips where I need formal and informal clothing, so the extra space is great.
Also fits perfectly above in overhead bin.
Other nice things:
- Can strap stuff to outside (most often this is my coat, but have also done stuff at airport).
- Good waist belt
- laptop sleeve built in
- Good passport access from top.
the Farpoint 40 is also good and a bit smaller.
I have the Transporter (
