Happened to notice this. I'm a platinum flyer, and I've never been on a flight when they ask "is there a doctor on board?" A friend I flew out here last year had a guy in cardiogenic shock when flying back to the mainland - she's a paramedic. A good friend of mine has been on 3 flights where they needed help - she's a neuroradiologist!Regarding "is there a doctor on board", earlier this year I was flying with my wife and they called over head for a doctor. No one responded so I stood up and took a look, turned out to be elderly women who was dizzy, nauseated and fell trying to make it to the bathroom. I did the ABC's and spoke over the radio to the airport with the pilot. Did vitals which were stable and I asked for the medical kit which was very weak, no AED. I started O2 and stayed with her until we landed. Not much I could do but the woman did well and I briefed the EMS when they boarded. When I walked back to my seat two guys mentioned "you did a great job" and I said are you docs and they responded "yup anesthesiologists." They asked me what I did and I said psychiatry and their jaws dropped. My point is regardless of what we do, start with the basics which even techs know, and just being there to help may be therapeutic with the limited resources you may have on a plane.
