Same, and I’m from Canada. Lots of international flights route thru the US. I have to make extra effort to avoid. Been doing that for 10 years. Just not worth the risk.
Yes there’s pre clearance in Canada. This would ease the border a bit. But there’s still a risk that something somewhere will go wrong.
The main reason I stoped routing thru the US 10 years ago wasn’t ICE. I didn’t like the way border agents were rude and disrespectful. I felt like I was being interrogated every time and didn’t feel welcomed there. So I decided to vote with my wallet and simply not fly thru.
