ATL-Atlanta, GA NOT all major airports have direct flights to DUB-Dublin, Ireland. SFO-San Francisco does not. Several US cities have such flights including New York (JFK), Boston (BOS), and Newark (EWR).
Alaska, Horizon, and United currently offer direct flights between the two cities. http://www.portofportland.com/NonStop/Search.aspx
No. Most airlines use a "Hub" system, which means that all the nonstop flights are either to or from a "Hub", and then you need to change planes and take another nonstop flight from the Hub to your destination. Sometimes you even have to change planes 3 or 4 times to get where you're going. For example, American Airlines hubs are primarily Dallas/Fort Worth (DFW), Chicago's Ohare (ORD), Raleigh/Durham (RDU) and St.Louis (STL). Also some others can be considered hubs, like Los Angeles (LAX), New York's JFK, and Miami (MIA). You're likely to change planes in one of these hubs, if you fly American Airlines. But this is true on most airlines, although the hub cities will be different. You're not going to find a nonstop flight unless you happen to be flying to or from one of the airline's hub cities.
Some cities in the tropical rainforest in North America include Puerto Ayacucho in Venezuela, Iquitos in Peru, and Manaus in Brazil. These cities are located within or near the Amazon rainforest, which is the largest tropical rainforest in the world.
The Major cities are San Juan ( The Capital),Bayomon, Carolina, Ponce, Mayaguez, and Caguas.
A nonstop flight from Detroit to Cairo typically takes around 12 to 14 hours, depending on factors like wind conditions and the specific flight path. However, it's important to note that direct flights between these two cities are not very common, and most travelers may need to consider connecting flights, which can significantly extend travel time. Always check with airlines for the most accurate and current flight durations.
