Hi FTers

I'm trying to book a United flight from ZRH to SFO return (two week trip) mid/end Dec. Dates fairly flexible. Every time I search on United.com I cannot find the United flight, just the SWISS flight. I would like to book the United flight as they have a more flexible baby bassinet policy up to 2 years whereas SWISS is only up to 8 mos old.

I cannot even find the timetable of ZRH-SFO flights. I reached out to UA Twitter and they just said the timetable is "on united.com" which is not helpful at all.

Any tips from FTers would be appreciated. Thank you
