We're looking for new luggage suitable for a 2 week trip. Any brand or other suggestions?
Too broad a topic. There are some people who can pack for a month or more in a carry on and others that think they need the biggest checked bag AND biggest allowed carry on for a 1 week tour. There are so many options for sizes, styles, and places to purchase them that you can go inexpensive or spend a mint. I just did a 20 day trip - river cruise plus extra days at beginning and end using a 24" checked bag - Travelpro maxlite bought from Tuesday Morning for about $60 plus a small underseat roller bag made by Aerolite - under $50 from Amazon. My husband is still using the Ricardo bag bought at Costco in 2014. It's looking a bit battered but still works fine.
I'll give you some thoughts on what we look for:
Besides the luggage itself, look really hard at what you are packing. Get a kitchen scale and actually weigh clothing and shoes. Items made from wool or cotton will be almost double in weight for a comparable item made from polar fleece, modal blends, etc. I can take 2 modal blend tops for the same weight as a cotton T and know that they can be washed out in the sink and dry overnight.
I love the hardside spinner suitcases. There are many great names in the line of luggage. I have a 29 inch from the Delsey Shadow line which I bought at Macy's years ago. I went w/purple because as Claudia stated black makes it more difficult to find when the luggage starts coming out on the belts. I do add a luggage strap around my suitcase, too, and use packing cubes that help a lot in keeping my clothes neat inside and also helps by giving me more space inside. I will say my first piece of luggage travelled many places before it had a gash in the front. Even thought the piece was many years old, Delta reimbursed me the price I paid which was more than the replacement piece I bought. I have smaller pieces, too, in purple from Delsey...love it!!
