Region of Waterloo International Airport - YKF

[plam]

The bus isn’t actually a flight, so I assume has more relaxed rules.  Not really a bus vs no bus thing since either way you needed someone to issue the passport.  Although, arguably much nicer in Waterloo.

It is actually true in a surprising way that the bus isn't a flight; I've tried to go through security at YYZ with a bus boarding pass and it isn't in the system. 

I will agree with creative that the bus isn't secure and shouldn't be considered "airside" for security purposes, even if screening were done at YKF.

Bags can arrive at YYZ from connecting flights, though, and I don't know the reason that the bus can't be considered a flight for that purpose.

Annoyingly, it happens all the time that I can't check in online for a 6am flight from Wellington when it's ticketed by Air Canada and operated by Air New Zealand.
