I had my Oly 4/3 gear in a camera bag under the seat in front of me. I forgot to take the bag and got off the plane. Fortunately I remembered the camera quickly and we were able to get back on the plane once all the passengers were off. Scared me so much, I switched to m4/3 so I could carry it all in my large purse and lose the camera bag. I had thought I could put the lenses in my suitcase, but now after reading this thread, I might be back to the camera bag. (sigh)
