Update: the 29” suitcase is too large to take on US airlines. For example, Delta limits checked baggage to be no larger than 62 linear inches (length+width+height). The 29” bag measures about 64.5” all together. Disappointed that this size is too large, because I probably would have chosen another luggage set. However, it still is a nice set and will continue to use the smaller two cases for flying. This is a beautiful luggage set! I was hesitant the the green color would be too bright for my liking, but it’s a very nice olive green. All three pieces move smoothly and although the case does give a little if you push on it, it feels sturdy enough for my sporadic traveling. Some things I love: -bottom handle. I had trouble finding hard luggage with a place for your hand to grip on the bottom. I love that all three pieces have this feature! -all three pieces have a mesh bag that can be added to the side to put a water bottle or extra things in. Based on the item description I thought it was just the largest bag that had this. I was happy to see that each piece came with the hooks and appropriate sized bag. (These are pictured in the left zipper divider in each top half of the bags) -the locks! I also struggled to find a set in which all sizes had tsa approved locks built in. All three bags have locks built in and feel very sturdy and well-made. They were easy to open the first time as well. Each bag has instructions on how to change the lock code as well. -built in pockets to the lining. All sizes have two zippers on the top lining, as seen in my review pictures. Even though I use packing cubes when I travel, the divided zippers will be useful I’m sure! The small zipper bag on the bottom half will be nice for any small or long things, like a flat iron or curling iron. -how the bags are divided. They are taller on the bottom and shorter on the top. I think this will be useful for packing for longer trips especially. It may also help my luggage to not be so top/front heavy, which has caused my luggage to tip forward in the past. -the retractable top handles. They feel sturdy and have different height adjustment features. The largest bag only has one because it’s so big, but the medium size has 2 height adjustments and the carry-on size has 3! -the other top and side handles. The edges move inward when you pick up the bag, which makes it feel like they can support more weight and not like the handle is going to rip off. It’s a small feature but I like it a lot. Oh and the handles on the side by the tsa locks can hook an umbrella! -the wheels. They’re so smooth when rolled across the floor! They will be awesome for going through the airport. Just make sure when you lay the luggage down, especially on the floor that the back 2 wheels are flat. I could see that causing damage to the wheels if they’re not layed out right. -expandability! Each bag can expand which was another feature that was hard for me to find. Many other sets I looked at only came with an expandable large bag. But I really wanted all 3 to have that feature. The zipper that controls the expanding is green so it’s easy to find. I have not traveled with any of these yet, but plan to take the carry-on with me on a flight at the end of January. I hope these pieces hold up well and last me a while! Overall, it seems well-made and each piece came wrapped in its own loose plastic bag, which I plan to keep them in to protect from any scratches or scraping during storage.
