Beware the UA one-stop via SFO; took that for a family holiday a year or so ago. Coming back they dump you, shagged, in a freezing cold all-facilities-closed terminal in SFO at oh-dark-thirty and leave you there cooling your heels, literally and figuratively, for four hours waiting for onward connection to New York
CO EWR-HNL nonstop is the way to go - worth it!
