Hi,
ZRH->YYZ->DEN on Air Canada connecting further in DEN to PHX on United (one ticket)
Connection time at YYZ is 2 hours, 20 minutes. Arrival on a Saturday at 4:10 PM, Departure at 6:30 PM.
Business / US resident / TSA Pre (not that it will help / Global Entry and hand luggage only
How tight/easy is a 2h 20m connection in YYZ? Looks as if there is a security check involved and as far as I can tell I don't need to fill out any Canada paperwork i.e. ArriveCan ... but I might be wrong
