I was on a flight YYZ -YVR and the Pax sitting next to me had a seizure.
One doctor on board the SD and also there was an offduty FA travelling
The Doctor and the off duty FA handled the situation.
It was quite scary but they handled it with great calm. I moved seat and the off duty FA & Doctor sat with the PAX . During my layover in YVR I went on Facebook and praised AC on the way the ordeal was handled.
Upon boarding my next flight I was magically upgraded to J . :-)
