I can only speak to my experience last month flying SLC to Costa Rica. We put two skis, plus jackets, handles, gloves into a sport tube 3 and it worked out great. Having worked my college days as a ramp rat at O'hare, I know the abuse bags get. It worked out great. For a slightly cheaper option you can go to backcountry.com and get the orange version for about $230. Just make sure you use a bungee cord from the end to the "locking" hole in addition to a travel lock. Those locks are not very strong.
