How long would it take to drive from Monterey Park/Rosemead/Alhambra to LAX?

If you have to get to the airport by 2:30 I'd leave an hour early just in case of traffic. I wouldn't push it if you're trying to catch a flight.

Eh, it's fairly unpredictable. Give yourself plenty of time. And I second the Union Station Flyaway idea.

According to Yahoo! Maps, it take about 35 minutes from Alhambra to LAX.
I would assume that you will take I-10, I-110, and I-105.
It's now 1:57pm and according to Sigalert, there is no traffic on those freeways.
I, however, would leave Monterey Park/Alhambra/Rosemead at 1:30 just in case.

here a idea might even save tyou some money and time
drive to he Union station (parked at the metro building)(on vingnes)
then for $7.00 you can take the flyaway to lax.
and i think the parking is about $6.00
now what time is your flight?
