Sure, MAGA fascists don't have to make a lot of sense, but what's the point of forcibly bringing in people you'd want to send out on a plane anyway, when it was planning to do that in the first place? I think that should be obvious to even the most faithful followers.
Anyway, as a thought experiment, if you love being seated on planes but you think US airspace stinks, you can go from Mexico City to Toronto via Bogotá and Paris or Madrid if you are okay with passing above Puerto Rico only.
Or, to avoid it completely, you can go to Panamá, Rio de Janeiro, Lisbon, then Toronto. Now to compare flight prices and travel times (won't include any layover time, price is lowest baggage tier, random dates in October)
- MEX -> YYZ direct: $387, 4h50m
- MEX -> BOG -> MAD -> LIS -> YYZ: $1827, 23h40m
- MEX -> PTY -> GIG -> LIS -> YYZ: $2583, 28h50m.
