Any thoughts on which is better connection out of IAD going into Kabul: Dubai or Frankfurt? 14 hours direct to Dubai continuing next day into Kabul seems more trying than 8 hour flight IAD-FRA with 6 hour flight into Kabul next day seems less wear and tear on the traveler. Dubai however seems to be favored route. Any reason for this?

How is the service on Safir these days?

thanks
