After some uncomfortable flights with just a standard foam neck pillow, I bought a Trtl. I haven't used it for a flight yet, but I've put it on to test it out, and I definitely feel like it's going to be very helpful. It felt a little strange at first getting it into position, but once I got it situated, it really did feel very comfortable. My husband went ahead and got one, and I gave them to my parents as gifts. Our 10.5 hour flight is in about 3 weeks, so I'll be testing it out soon!
