ok, about the liquids. I do have a pouch that is padded and waterproof. I put everything in there and inside my luggage. Try to pair down to the minimum and also, avoid yourself the aggravation, don't take glass bottles. Airlines no longer allow fragile tags, unless you are flying business class or better and these luggages just fly thru the air.
I am a somewhat light packer so I don't roll stuff, just neatly fold my clothes, but look up rolling clothes / packing, if you want to see it. It is basically rolling your clothes so they wrinkle less and you can fit more. Also, most seasoned business travelers have only one piece of luggage and a purse or laptop bag. Avoid yourself embarrassment and don't be the lady with the multiple bags. Also, try to keep your bag light. when you travel with men especially, they usually offer to handle your luggage. You don't want to be the one with the ton of bricks bag... no, no.
As a side note, I always suggest sweatpants and a tee for sleeping rather than a nightgown or pjs. there was a fire at one of the hotels I stayed at once, and had to leave my room, to meet my colleagues in my heart patterned pjs... never again.
My suggestion always is to take the less amount of shoes as possible. Those are heavy.
About airport security, et al. You got to take your shoes off, so try to have something you can easily take off. Also, avoid clothing with metal details or excessive hardware. That will sound of the metal detector, so It will slow everyone down.
The key for business traveling is to not slow anyone down...
If you are working the same day that you arrive, remember you might not have access to your luggage until Nighttime, when you check in to your hotel. when that happens, I make sure to have a travel size toothpaste, toothbrush and other toiletries, maybe a small lipgloss in my purse. You do not want to open your luggage in front of colleagues to get stuff, and have your undies flying out of something. no.no.
That is all I can think of for now, but ask away. I have been traveling for business, at least a week a month, for the past 10 years. Trust me, I've done each and every mistake unimaginable.
