business travelers - luggage recommendations?

I travel a lot, but never with a suit.  My FAVorite piece of luggage so far is my new hardside spinner from ebags:

There is a carryon and a bigger size.  It made it through it's first trip (a long one, lots of airports) without a blemish.  This has never ever happened to me. It's very light weight, super easy to push or pull, and the compartments are very nice.

Just as a piece of luggage, this is really awesome and efficient.  

When I traveled for work, mostly by car, I used a carryon sized Samsonite.  They usually come with suit hangers so might be worth checking out.  They look a bit worse for wear, but I have used them on hundreds of trips and still do. 

I have to travel internationally for work often so i will give you what it works for me and perhaps you can get some ideas even if my set up doesnt work for you.

If i'm traveling for 3-5 days as you mentioned you would, and there is the need for more than one suit what i normally do is a small carry on for casual clothes, running shoes, etc, then this bag for the suits and shirts

I put the bag on top of the carryon and holding againts the handle and 99% of the time i get to take both with me as a carryon without the need to check a bag.

If you are ever in a 1 to 2 days business trip, and one suit is more than enough i highly recomend this bag:

It looks great, you can put your computer and the essentials for a couple of days.  I used this setup for quick trips where i dont bother with workout clothes etc.

I travel alot. I think the best luggage decision I have made was to get a horrible burnt orange color carry on size. No one else would choose that color. Seems like most of the time I have to "planeside check" it these days. I will admit I give up some style points on the color, but I can always identify mine immediatly. I can always make up the style points on the rental car; I'm the first to the lot due to everyone else trying to find their black bag at the planside check bag sorting scrum. Good luck on the new gig! Consider an odd color; just not burnt orange.

Oooh, you're right on the border of whether you can get it done with a carry bag or need to check a bag. If you're traveling the same place you can get it down to a rollaboard bag by leaving your suits/dry cleaning at the hotel or dry cleaner, so all you're really flying with is toiletries. 

But...if you're going someplace different every week, your answer likely changes based on whether your trip is 3 or 5 days, more specifically, based on whether you need one or two suits.

One suit scenario: This is what I do. I can get one suit, a pair of slacks, 4 shirts, undershirts/drawers/socks dress shoes, 4 workout outfits, running shoes, swimming gear, toiletries in THIS BAG.  I've had it since 1998, it's probably flown 2M miles with me. Quality and service are outstanding. Plus you can find it amidst the sea of black ballistic nylon bags. Still kicking. 

Two Suit Scenario: I'd score a rolling garment bag...that will house two suits, shirts, shoes, etc. Then, you can score a rolling case (or matched case to the garment bag) or a carryon to house workout gear. Don't have a recommendation there, but the top-of-the-line Samsonite is Tumi-Quality without the Tumi price.  If I needed one, that's what I'd get. I'd also avoid getting two wheeled cases. Difficult enough to horse one wheeled case through an airport, but with two, it gets a lot harder. Look for a system where one case has the wheels, the other somehow attaches / hangs / integrates to it.  

Last Protip: when you transport your suits and shirts, regardless of case, leave them in the plastic from the drycleaner. Presto, no wrinkles.

Lots of good advice so far.  For my $.02.  I have a blue suitcase (because everyone has black and blue does actually stand-out).  It's a Delsyn with the four spinners on the bottom.  It has a separator for suits/coats. 

I carry it on any length of trip.  I like to have my stuff in the same bag no matter whether I'm going for 2 nights or 5 because if I go for 5 the next week and I forgot to put something back in my spinner, it was something crucial like a razor or deodorant.

For my computer bag, I paid a little more and got a Briggs and Riley that has a lifetime guarantee on it.  My dad had an 11-yr-old one that the zipper broke and they replaced with no questions.

I would also recommend Bose Sound Canceling Headphones.  A 737 cabin runs at between 80 and 90 dBA.  That's hearing-damage level.  They do actually help with jet lag too.  When I have forgotten them, I can notice a clear difference.

I hope you know what you're in for.  I traveled from October-March almost every week.  It gets really old...

I also travel weekly for work for at least 4-5 days at a time.   I never have to check my luggage, unless I'm bringing home some BBQ sauce or a bottle of wine.  At this point, I could pack my suitcase in my sleep.

I love my Travelpro carry-on.  It's a moss green color and in 4 years, have only seen two other travelers with the same suitcase...it's SO easy to spot.  I've been using this one for 2+ years and besides losing a few of the zipper pulls, it's still in good shape. 

I recently went through 2 laptop bags in less than 6 months (zippers blew out both times) before I decided to splurge on a Tumi.  I don't regret it.  I've had this one now for over 6 months and it looks brand-new.  Also, I highly recommed the check-point friendly option.  It's nice not having to take the laptop out of the bag.  It might not seem like much...but in the long run, it really does save time.

Edited to add:  I also take along with me a super light weight REI duffle bag (one of those nylon things that can fold down into it's own pocket).  It packs really small, but is big enough to hold my clothes, a towel and all of my shower items. If you're planning on going to a gym outside of your hotel, you need something to carry your stuff.
