Love United’s Zürich-San Francisco nonstop. It makes getting from Central Europe to Portland very easy. Coupled with a nice flatbed seat, good food and drink, and very nice service, it is my preferred way to get to the USA. Can’t wait until they put the new Polaris seats in the 787s. Customs and Immigration at SFO is always a breeze and United’s Polaris Lounge is accessible to and from the USA. It is the best lounge in the USA and has arrival showers which I love. So glad United offers this plus LHR, FRA, CDG, MUC and AMS nonstops toSFO.
