Flights from Newark to San Francisco: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Newark to San Francisco 
MitchellFlew with United Airlines-Apr 2026
security access line for Premier access was very reasonable, process was less than 10-15 minutes. Leave time for dropping off a rental car - is a bit of a walk and then AirTrain transfer due to the current construction - so allow time for less stress. take advantage of the tables in the boarding area for charging devices or doing work.
