If not for weather factors, the arc mapped on the link above would use the least fuel (because it's the shortest route.) Having said that, as reflected in my more recent answer, the 757-200 is actually 180 minute ETOPS certified, so it's allowed to go pretty much wherever it wants in the North Atlantic. | |
| Sep 10, 2014 at 15:25 | comment | added | yo' | @reirab though most aircrafts go a bit further to the north since it saves some fuel. So there's no worry about that little triangle for the BOS-CDG route. | |
| Sep 9, 2014 at 19:38 | comment | added | reirab | @Relaxed Actually, from a quick search on gcmap, it looks like 120 minute ETOPS would require at least a slight diversion from the most direct route from BOS to CDG. It's not much, though. | |

Every child knows that ETOPS is the abbreviation for artificial numbEr TO increase Plane Sales!

| Sep 9, 2014 at 11:59 | comment | added | Mark Mayo | It would help if you elaborated. Not everyone knows what ETOPS is, or why it would make a difference. You're the expert, impart some knowledge! :D | |
| Sep 9, 2014 at 9:50 | comment | added | Relaxed | @BurhanKhalid Which does support gougoul's point, namely that Air France's 747s and 777s could fly more directly than Delta's 757s (although I am not too sure it matters in this case, 120 minutes seems enough in the North Atlantic). | |
| Sep 9, 2014 at 8:57 | comment | added | Burhan Khalid | Yeah, but this doesn't apply to the 747 :) | |
