Local driving advide needed
 

I have a 5:45 flight out of LAX tonight. Leaving from Disneyland. Have a car to return.

1) Any advice on when I should leave to comfortably be in the airport by 4:45?

2) Any route better than the Google Maps one (91 to 605 to 105)

That route should be fine, but if you have a chance to check traffic before hitting the road you should. 91 to 710 to 105, or 91 t0 110 to 105 are possible alternatives.

Traffic SHOULDN'T be too bad before 5. I'd be surprised if it took more than an hour, but if it were me I'd give myself an hour and a half to be safe. But I always err on the side of early when going to airports, so if you'd rather be a little bit late than a little bit early, an hour is probably fine.

Are you traveling alone? 710 lacks a carpool lane, so Keep that in mind as you consider alternate routes

I recommend a teleporter.

Traffic was insanely light this morning due to the MLK holiday (I guess?) My normal 40 minute commute took 25 minutes, which is lucky since I left 25 minutes before I was supposed to be at work.

Yes alone. Forgot about holiday traffic so hopefully not bad.

Technically speaking, from Disneyland, you would take the 5 to the 91. But otherwise, the info above is sound for today. If today weren't a holiday, I would allow for more than an hour.

I still would... in the afternoon people will be returning from wherever they were all weekend.

Do cars with two passengers get to use the carpool lane? If so how much of a difference would that make for a trip from LAX to DLR on a non-holiday Tuesday evening round about 6:30pm?

6:30 pm? Shoot yourself now.

Only 1 passenger (2 total occupants) are required to use the carpool lane. And it would make a significant difference at that time. Still going to be slow, but it will definitely help a lot.
