I have taken mine a few times. I found a rolling backpack and I can fit it under the seat in front of me fairly easily. I prefer to put it there as I dont' like to hoist it over my head! (I have visions of the overhead bin coming open in flight and my sweet Fw clobbering someone on the head!) 1st time I traveled with her, she got swabbed for drugs (she was SO humilitated!) and on the way home, they never even took her out of her bag. As she traveled thru the xray machine, the tech popped his head over the top and exclaimed "thats a sewing machine, isnt it?" I'm so glad he recognized it! Restored my faith in mankind! lolol
