Let the insanity begin: 2 day mileage run YYZ-NRT-SIN-NRT-YYZ

Won’t even be leaving the airport, as I have a 6 hour room booked inside SIN airport (S$47/US$38 for budget single, i.e. shared bathroom)

19,448 miles round trip.

Interestingly, YYZ now has a Nexus security lane even at the international (non-US) departures, at least in T1 from where AC flies.
The Maple Leaf lounge puts out lunch (and alcohol) at 11am, so I’ll have 15-30 minutes to enjoy that before heading to the gate.
