United Airlines and Hawaiian are competing for low fare travel from San Francisco to Honolulu at $310 round trip for departures into March 2016 on nonstop flights.
American comes in with a low $327 routing via Los Angeles LAX or Phoenix PHX.
This is a fluid situation. As I was writing this post the low fare dates changed from only Tuesdays and Wednesdays to include many Mondays and Thursdays.
United Airlines low fares are weekdays from January 20 to March 9.
Hawaiian Airlines is $311 round trip on most of these same dates. Hawaiian is generally lower than United Airlines for departures from SFO other days of the week.
American Airlines is perhaps the best deal of all with $327 round trip fares on weekdays and $362 fares on many weekends when United fares climb to around $481 round trip.
