Yes, I've fainted on a plane. August 5, 2000. JFK to Shannon, Ireland.
I felt fine that day, really great. It was gonna be a great family reunion trip (16 of us) to see where our ancestors came from. Since we departed shortly after dinner time I decided to have a glass of wine before I took a little nap. I successfully finished off one of those teeny 4 oz bottles of red wine then slept for about 3 hours.
I awoke because I felt a little airsick. I searched all the seatbacks near me and found no barf bags. UGH. Must...get...up...and...walk...to...lav. The nearest rest room had a long line. By this time I knew I couldn't wait and asked a stewardess for a barf bag. Her response: "Oh, you'll find them back at your seat." Without the energy to dispute her, I turned and walked back toward my seat.
I never made it. Fainted dead away right there in the middle of the aisle. When I came to (about 2 minutes later) I was vomiting nonstop and didn't have the strength to stand, much less walk back to my seat. Some passengers eventually moved me to the galley floor so I wouldn't be blocking the aisle. A doctor on the flight tended to me for about 2 hours...until I could be removed by EMTs and taken away in an ambulance. (Oh, for the landing, they insisted that I couldn't remain on the floor. Duh! So, since my coach seat was out of the question, I got to experience landing in Aer Lingus first class. NICE!)
The nice staff at Ennis Hospital in Ireland couldn't find any cause for my fainting spell, but did determine that my fall caused a concussion. (Nearby passengers said my head bounced.) Back at home after the trip I checked out fine as well.
Then, in 2003, I fainted again (but not on a plane). This time was also after having a glass of red wine. Needless to say, I haven't had red wine since. I just figured it "disagreed" with me.
But then, just last month I was having dinner at a friend's house and she offered wine: red or white. I said, "oh, white please. I can't do red." Her reply: "Oh, are you alergic to sulfites?"
At that point a bell went off in my head. I'm allergic to sulfa antibiotics. Red wine contains sulfites. Although they're not the SAME, they are similar. I now attribute my red wine fainting to a sulfite allergy.
By the way, I've been a "fainty" person my whole life. The incident on the plane was probably #10 overall and there have been others since. Low blood pressure, I guess. That's probably why I checked myself out of the Irish hospital against doctor's advice and proceeded to have a marvelous time on the trip...even with a monster headache.
