People have always been advised to arrive 2 hours before US bound flights. Nothing new.MonctonMan wrote: ↑ "Enhanced Security" for flights destined to the USA. People are being advised to arrive 2 hours early. Since most Canadian flights fly over the USA, it strikes me as a bit odd they'd target flights landing in the USA, but I don't make the rules.

What strikes you as odd? It is for flights landing in and taking off from the US. Flying over has no consequence to US border or Homeland services .
