I'm going to be flying with a large bike bag. Will easily be under the 70lb limit, but I'm going to be very close to the stated limit of 115 inches (add length, width, height together). It's going to be 110 inches so I'm worried with the wrong person at the desk I might not get the back excepted. Any have experience flying with a bag close to the limit? I am EP if that helps any, but probably won't. AA website says: "Checked bags over 115 in / 292 cm in total dimensions (length + width + height) are not accepted."

Edit: So my question is does anyone have experience flying with a bag so close to the limit? I'm afraid of getting to my destination and then not being able to bring the back back home.
