since hamas leaders are in Doha and ongoing Negotiations are there, it could ..... just maybe..... be something, someone heard whispered around some corridor, about retaliation action iran>< Israel happening soon, not today, maybe, whenever...... which would affect the usual flight path.
even if untrue, we here at FT are not the only ones seeing these different routes and it keeps the people involved guessing and thinking the same thoughts.
or very simple: QR would not change their routes if not someone higher up told them to. some information floating around somewhere to make them change their flight plan.
