Ah, sorry. The only stops I must make are DAC and IAD. I couldn't get the RTW calculator software to generate a valid itinerary returning to OTP directly from DAC (too many connections? Bad scheduling?) so I had to insert an intermediate stop, in this case Cairo. Problem is there ain't much West of DAC and East of OTP for *A customers to connect through, at least not that I can find. I'd love to fly back from DAC to OTP as quickly as possible but couldn't make it work. CAI is an OK stop, I used to live there and have friends there, but at that point I think I'll be ready to just get home.
