Hello,

I was wondering if someone can help me out here. I emailed turkish airline ticket sales office and they said the first segment (BOS to SFO; UA 207) of the below flight is unavailable. They mentioned they could see another flight (UA 433, 6:00 am - 9:55 am (6h 55m)) which I would rather not book as it will make my layover in SFO longer. I called the call center twice but they are unable to book any united airline flights on phone. I was wondering if anyone knows why they might not be able to see the first segment. They both have economy saver availability. I can see the same flights on aeroplan available as well. Thanks!
