For the Style-Minded
You've got to admit that if you're looking for stylish luggage, Orla Kiely is your first stop. Of course there is a pricetag attached, but I read reviews and expect quality with that dollar sign. From what I read, people are passionate about their Orla Kiely luggage-wear. And you probably wouldn't get it mixed up with others as it came out at baggage claim.
All Black and Business
So, it doesn't have to be all black. Tumi has some really great colors right now, especially in the Women's line. My dad works in international business - he has more frequent flyer miles than anyone could dream up. My older brother is following in his footsteps and both of them use Tumi luggage. It's quality, it's reliable, and it holds everything you can think up (and more) without bulk. To be quite honest, if I were seriously shopping for luggage I would choose Tumi. Granted, it might be boring in black, but maybe you could choose a fun luggage tag (and carry on)?
Personally, I'd go for anything from Hobo Bags right now, but sometimes a cute laptop case and a lightweight backpack work well allowing you to keep your hands + arms free.
