I am planning on traveling to Dubai from IAD muliple times in the next few months with my father. Ideally we would take the JFK-DXB route that Emirates has, however my father seems to prefer to avoid a long, 12+ hour flight that a NY to Dubai flight would include (although that defeats the purpose of taking Middle Eastern airline). Aside from booking separate flights from IAD to London/Paris/Frankfurt and then booking a ticket from there to Dubai with that country's airline, are there any ways to connect in Europe through an airline partnership agreement with Emirates?
