As is well established on FT, there is the law/rules, there is the AC interpretation of the law/rules, and there is the individual AC employee's interpretation of the law/rules. The FA I asked on YYZ/BOS the other day (while seated beside a 20 yr college student returning home to the US) told me that since the flight departed from Ontario, alcohol could be served to anyone 19 or over
He/she was wrong.
I cannot speak about the lounges, but
onboard the a/c the min. age is 18. Regardless if it left from the US, Ontario or anywhere else. The exception being for minors can be served alcohol if travelling with a parent or guardian who consents on
international flights.
no reason for further debate as far as the policy on the aircraft.
