If you're going to have to check it anyhow, bring a real suitcase and put it inside. A pack like that is not meant to survive the abrasion and impact it will get in airline luggage handling, straps or no.
Soft luggage of any kind is a single-use item for air travel. It WILL be dragged far enough to leave a hole, and it WILL be dropped/have stuff dropped on it hard enough to bend or break the frame. We learned the hard way that it's cheaper to buy hard sided luggage to begin with than to replace them every single trip.
If you have a cheap worn-out duffel that you were about to toss anyway, that should be enough to protect it from abrasion and from the straps getting hooked on other things. I don't know what kind of an internal frame that pack has, but I would make sure to protect that at least with a couple of cardboard boxes and styrofoam at a minimum, if a suitcase isn't in your budget.
