Mate if you fly on the same route as me ... you have a good chance.
Had a medical problem right in front of me on a my London leg of the flight.
This was about the 10th time (twice fatal).
EVERY flight always had a Doctor (or two) when they called .. amazing.
This Indian (lady) Doctor was great with the pax and she recovered well during the flight. (Low blood sugar made her pass out in the lavvie).
Cheers
