I fly to Dallas and Los Angeles regularly on Qantas and Virgin and every flight has been in Y. This is not an an ideal way to spend ~14-17 hours. No way in hell would I sit in this thing to London in Y. The next obese man or woman who sits next to me is getting a deflating puncture to the abdomen. The width of humans in modern era (Americans followed by Australians), is truly a thing of nightmares on reduced seat width.
