US travel has not returned back to 2019 levels, besides FL.
AC is targeting US passengers to transit via Toronto/Montreal/Vancouver to Europe/Africa/Asia. In the summer it works super well, but in the winter when traffic dips to those destinations, it's really hard to serve destinations like Pittsburg, Raleigh, Seattle, etc. And we all know where QCers go in the winter, FLL/Miami, not Seattle.
