Black and Blacker for airline travel, definately!
TravelPro (Black) is the luggage I have used for nearly 10 years. We have five sizes, the hubby loves the expandable and I use the small Pullman for short trips especially if it going to be checked in. I always tie colorful season ribbon on either side of the pull handle for easy spotting.
I love my Kate Spade lepard print duffle for trips where I don't check in luggage. It is easy to spot! (no pun)
