My family and I have been traveling with our LOs for a while now, but every time we travel we borrow luggage from my DH's family. Sometimes the luggage is great and fits everything, other times the luggage is small and bad quality. Honestly, I think it is time that we get our own quality luggage since we travel at least twice a year by plane as a family. So I was wondering if any of you have recommendations for brands or types of luggage that you swear by. I am looking for luggage that fit the following criteria:

1. At least 21" tall since this luggage will always be a check-in and will need to fit clothes for all 4 of us
2. Can roll but does not have to be 360 degrees
3. Multiple ex/interior pockets
4. Expandable

Thanks everyone!
