Sure why not.
My most recent one was a few weeks ago, Dubai to Atlanta. Older Indian male had syncopal episode. Lead stewardess said I have 10 minutes to make a decision on whether or not to divert as we will be too far over the water at that point.
While kneeling over the now conscious patient, I have a man try to insert himself between me and the patient. I do not care who you are, once someone has already established rapport and appears to be competent, you do not interrupt. You may add on in a bit if you like, because any provider can clearly see there is no dire emergency.
Anyways, he asks what I am and when I inform him I am a paramedic, he made a face like he really did not know what it was and then countered with "Well, I am a doctor". Whatever dude, I am not going to argue or fight in front of anyone, I much rather be sleeping still but this occurred 3 seats in front of me.
I quickly briefed him on what I had ascertained and he then asked for the patient medication list. I asked for a glucometer and BP cuff which they attendants promptly brought. I handed the cuff and stethoscope to the doc and I went about getting a BGL.
After finishing the finger stick, I noticed the doc looking rather puzzled over the highly complicated BP cuff, so I took it from him and did it quickly. He seemed very nervous with everyone watching, but hey man, you wanted the show.
After telling him the BP (the pt did not speak English very well), and his medications were all gibberish to me, the "doctor" started insisting that the pt needs a NTG tablet. I asked why and he said he just needs one. At this point, the stewardess has seen the difference between me and the doctor and the faces I was making. I quickly gave them a look like WTF, this guy is not a doctor. The doctor then asked for Atropine. It was at this time, that I said to the stewardess that this guy needs to take a seat, it is crowded here and I need room to work. I wanted to sit the pt up and do some orthostatics.
The attendant asked the man to take his seat, thanked him for his help and he seemed very confused as to why but they insisted several times. I think he finally got the hint and went back to wherever he came from. The pt's BP was fine, pulse strong, regular and with basic English and gestures I made a judgment call that the pt was fine; I then told the attendant to relay to the pilot to continue on. They asked if they could tap me on the shoulder during the remaining of the flight (8 more hours) should anything arise, instead of asking for help over the intercom. I agreed, went back to sleep and nothing else came of it.
This is just one incident, there have been a few others. However, there has also been times where there were some pretty kick *** docs on board and jazzy nurses as well and everything was fantastic. The joys of international flying on a frequent basis...whoo hoo!
