YUL/YOW -> YHZ -- US restrictions?
 

Hi,

staying a week in Ottawa and was pondering for another week around Halifax or NF. Given a simple map, the flight YOW->YHZ would cross US airspace.

I vaguely remember that the "full game" (paperworks/ESTA) like when actually entering the US would apply - or was that only right after IT?

PS: German nationality/passport.

Absolutely not. YOW-YHZ is a Canadian domestic flight and there is no US paperwork to be dealt with / immigration to be cleared etc.

Many Canadian domestic flights stray into US airspace every now and then - this does not change the passenger documentation requirements.

...however, if the flight crosses US Airspace the passenger manifest, including nationality details, may be sent to US Homeland Security.

Most passengers would never even know it's happened, however.

How do they do that, if someone is flying on their driver's licence?

Thanks.. I think my memory came from people reporting flights from Yurop to South-America (where a potential emergency would require landing in USA)?
