I'm planning a trip from DC to Portland at the end of the month. In looking to get on my first triple seven (!!), I'm thinking about the following itinerary, on either Tues. 6/28 or Wed. 6/29:
UA 975, IAD-SFO, 5:21p-7:55p
UA 373, SFO-PDX, 8:51p-10:32p
Is 56 minutes enough time to connect at SFO? I'm also not familiar with IAD's evening rush (I usually fly out of DCA or BWI), so I am wary of my first flight being delayed. Also, might my 777 arrive into the international terminal at SFO, making my connection even shorter?
Thanks for any assistance!
