Given a travel related situation, and given a specific question about the situation, summarize the question into a title

I noticed that my flight going east to west took almost an hour longer than when coming back from west to east in continental US. What is the reason for this?

Why is a flight going west longer than the same flight going west to east?

Some Islamic countries in the middle east has got a long history of trying relationship with the west, and with terrorist attack of ISIS being a real threat to the world, would travelling to middle east put me in some kind of monitoring list of EU? Would that travel history bring me trouble if I need to get through EU immigration?

Can the history of travelling to middle east (Iran) hinder you traveling to EU again in the future?

I'm going by bus from Saint-Georges to Cayenne, passing through Roura. Is there any kind of public transport or scheduled service from any of those places to Cacao? Rome2Rio and other sites recommend going by car, but I was hoping to find something cheaper.


How can I get to Cacao, French Guiana?
