Probably in a backpack or suitcase or something. I travel with iPads and have never had a problem because I’m careful not to risk them ending up that way.

I once worked as a tech at an Apple Store and I would have said that it takes considerable force to bend them and wouldn’t cover it under the warranty. But that was before AppleCare extended to damage (late 2000s), so I dunno what the policy is now.

Edit: sorry that happened to ya.
