I have a TravelPro 20" rollaboard. It's great! I've found it fits in just about every overhead bin I've ever tried. Some 21" bags do as well. I'd not get one larger than 21" as other than the fact that it's rude to put a bag into the overhead sideways a larger bag also increases the likelyhood that you'll have to check it due to lack of room.
