Checked MyItineraries today and my previously booked NRT-JFK flight in November is now NRT-IAD-JFK. There is a message for me to call reservations to confirm changes. Like many others, I have a severe allergy to all things IAD, so my question is, do you think they will allow me to do a NRT-SFO-JFK, or NRT-ORD-LGA route instead? Thanks in advance for any comment/suggestions.
