The Toronto routing
Toronto to Paro is one-stop. We recommend Singapore Airlines YYZ–SIN with Drukair SIN–PBH the following morning (the cleanest connection; Singapore is the premium hub stopover); or Cathay Pacific YYZ–HKG with Drukair HKG–PBH (slightly shorter but the Hong Kong hub experience is more business-traveller-oriented). The hub overnight is your booking on your terms.
