Routes that usually fit the A-China-B shape

  • SFO -> PVG -> ICN
  • LAX -> SHA -> NRT
  • JFK -> PVG -> HKG
  • SFO -> PVG -> SIN

Common mistakes

Routes that need a different plan

  • SFO -> PVG -> LAX, because the onward region matches the origin country in this simplified check.
  • JFK -> PVG -> JFK, because it is not an A-China-B shape.
  • SFO -> PVG for 12 days, because the stay exceeds 240 hours.
