We will be traveling by car from downtown SF to LAX on Sunday April 20th (Easter). We are staying in a hotel near the airport in El Segundo and fly out on Monday at 1 pm. I am afraid of running into tons of traffic on a Sunday night. We are flexible on what time we leave SF. Will we encounter tons of traffic on that route to LAX? It doesn't look like there are very many options of expressways if we do run into tons of traffic. Any suggestions as to time to leave or alternate travel routes? Thanks!
