I looked a while back for my wife, whose travelling long haul rather more for work. If you want carry on that you can live out of for a week, then there are loads around, but after looking at websites for cabin crew and people who travel a lot for work, Travel Pro
http://www.crewoutfitters.com/brands/travelpro.html (especially the 9
http://www.travelpro.co.uk/showbrand.asp?id=23, which pretty much discountinued, but that 20in bag is a good price) and Luggageworks
http://www.luggageworks.com/ were highly recommended by US aircrew. The 22in ones are just small enough to be carry on, and are apparently really tough - they have to be, if you fly for a living. Not cheap, and Luggage Works (which were once known as Purdy Neat Luggage!) is very much US based. On the other hand, if your passing through an airport where they have a shop (and there are a number of US retailers who stock both brands that also have airport stores), or can have an item delivered to your hotel in the US, why not go for it. Travel Pro is available here, but buying in the US would be generally cheaper, and
some online stores ship to the UK.
What I love is all the other stuff you can get for cabin crew luggage,
http://www.stopoverstore.com/ - you first wonder why you need a cooler bag, until you realise that being cabin crew these days isn't quite as glamourous as it used to be, and bringing along your own pack lunch is often now standard.
However, when she was in the States a couple of months back, she realised that she needed a bag for a laptop, paperwork etc that she could carry comfortably (she was knocked off her bike by a car a couple of years back and her wrist got busted, and its been weak ever since). She spotted one of these
http://www.sears.com/delsey-absolut...p-01498783000P?prdNo=6&blockNo=6&blockType=G6 on sale, and reckons its great. Its a roll along (so she doesn't have to carry it), so easy to use on the train, plane, etc, but small enough for easy carry on. You can get a fair amount of stuff in it, perhaps just enough for overnight with perhaps a suit bag. Certainly fine for one day meetings, etc. They dont do that one anymore, but there are loads like it around.
If it was me, I'd probably go for the Travel pro option - you can get a suit or two in one, etc. And you can always use a tote for a laptop, etc. But there is loads of choice, and its what you want.
If your travelling long haul, and you get cold, and either worry about the mankyness of the airline blankets, of find there aren't any at all, go for the Westin Travel Blanket.
http://europe.westinstore.com/en/bedding/duvets-blankets/travel-blanket.html Not cheap, and it sort of looks like a cheap pillow when packed, and a cheap 4.5 tog duvet when opened, but my wife swears by it. She hates being cold, especially on planes, and I came across it when she asked me to find something better than the bog standard fleece blanket - One or two of the US airlines were using them for 1st class passengers, who were then nicking them!
http://www.flyertalk.com/forum/unit...blankets-purchase-discontinuation-merged.html She gets very jealous looks when she uses it on a flight, and if you put it in a compression bag, you can get it down to the size of a smallish sleeping bag compressed, so it fine for carryon. She also keeps nicking my Alpit Mission packs bags -
https://www.alpkit.com/products/mission - a bargain, and really useful.
