If I tell the flight crew that I am having a medical emergency, then it’s a medical emergency. The flight crew doesn’t get to diagnose medical conditions unless they want to get sued. That’s not something to take lightly.

Case in point, after a few days of norovirus recovery I was traveling back to Florida via YUL. Prior to boarding, I started to black out and as I approached the gate agent to ask for help, I lost consciousness and fell. Lucky for me, a doctor has been watching me and rushed over to stop my fall and hitting my head on the floor. I literally dropped right in front of the gate agent. Of course being Air Canada, the first thing she did was pick up my boarding pass, remove me from the flight and clear a standby while the doctor and others were screaming at her to call the paramedics which she finally did - I ended up ok and flew the next day but you can bet I would have sued them up the keester and beyond if I had any serious issue because of her delay getting help. Airline employees don’t get to decide what is or is not an emergency only to make sure they deal with it appropriately upon being informed.
