Bike box/case recommendations

I’m looking to buy a box / case for my bike because I’m going to be doing a bunch of flying in the next few years and I want to bring my bike with me. Does anyone have a recommendation for a brand or style of case that I should look into or avoid? I’m thinking the smaller/ more compact the case is, the easier its going to be for me to drag it around…

they all are pretty damn big, forget “smaller and more compact”. I did a little research when I got mine, and the Trico Ironcase seemed to be the cheapest, most sensible option, as of 3 years ago. Haven’t looked since then. It works, I got it for less that $250 online, my only grip is that I wished it had some handles on the side when I’m hauling aroudn my downhill bike, but you can just hoist it by the straps. It’s taken bikes with me all over the world, and still works just as good as it used to.
