Yes... I know this is a dreaded basic economy fare, but even still it's an excellent price for this route. If you need access to the overhead bin or want to check a bag, it's only $50 more roundtrip, making the total $182 -- still a steal.
Tickets at this price can be booked for travel as soon as next week through the middle of November. If you need to travel outside of that time frame, like in the winter, you'll see flights just a few dollars more through February 13, 2019. Flights are available daily, but you'll have the best luck with mid-week departures, no minimum stay is required.
Searching on United's site, I found seats departing LAX on Saturday, October 6 and returning from MIA on Wednesday, October 10, 2018. Other dates are widely available in the fall, but it's tougher to find these prices on Fridays and Sundays.
