One of these was announced 2 weeks ago but didn't make it to this forum. All three services will be operated on the 787 Dreamliner (Boeing version).
SFO-Tel Aviv starts March 30, 2016 with 3x weekly
SFO-Auckland starts July 1, 2016 with 3x weekly, expanding to daily from October 2016
SFO-Xi'an starts May 8, 2016 with seasonal 3x weekly. This was announced on Sept 22nd.
The SFO-AKL service will be "in partnership" with Air New Zealand (NZ). NZ had previously vetoed UA operating to New Zealand under their code share agreement. I can only assume that they've relented in return for NZ launching AKL-IAH.
It looks like UA is putting those 787s to good use and going for ultra long haul business on new routes.
