I'm sure there's enough demand to fill a 737-700 for a US bound flight from secondary cities like Asuncion, Paraguay or Kaohsiung, Republic of China (Taiwan) or Douala, Cameroun. Why not!
Asuncion via Georgetown, Guyana to Houston Hobby or Fort Lauderdale
Kaohsiung via Sapporo, Japan and Anchorage to Chicago Midway or Oakland
Douala via Barcelona and Keflavik to Providence or Islip
Let me have boarding pass A32! And give me my 1 bag of peanuts and a snack box with Ritz crackers and Wheat Thins!
