For travel over the 4th of July holiday, fly nonstop from San Francisco to Los Angeles for $235 roundtrip on Southwest.
I found flights departing San Francisco SFO on Tuesday, July 2, returning from Los Angeles on Saturday, July 6.
You'll find lower fares available for non-holiday travel.
This fare includes a carry-on bag, a personal item, and two free checked bags.
Southwest has an open seating policy, which means there are no assigned seats and you'll get to choose your seat during boarding. The order of boarding is determined by the time of check-in so check-in exactly 24 hours before departure or pay for priority boarding for a better choice of seat.
You'll find similar fares on other airlines like Alaska, American, Delta, and United, but keep in mind those airlines will have Basic Economy restrictions and don't include any checked bags. Southwest has the advantage of two free checked bags and no change fees.
