I flew IST-IAD yesterday and was surprised by the flight path as it added 2-3 hours to the flight. In Europe, instead of heading toward Germany/France and just south of UK, the plane flew north toward Sweden and north of UK. What's the reason for this? From IAD / KIAD), USA - Virginia">IAD to IST / LTBA), Turkey">IST, the flight path was much more reasonable (going through Germany) and hence the flight was 2-3 hours shorter.

Actual routes on such long sectors may deviate considerably from Great Circle taking into account winds.
Crossing the Atlantic Ocean westbound often takes northernly routes avoiding prevailing jetstreams resulting in headwinds.
