It took forever for our Uber driver to find us at LAX. But we had a good idea of why based on our experience of taking Uber from my SIL's house to the airport. It takes the drivers forever to get through the airport loop. We took Uber from Redondo to LAX. It took us almost as long to drive through the loop at LAX as it took to drive from Redondo to the airport. About 20 min each part, iirc. More painful because our Uber driver was a talker whose hobby was extraterrestrials in the American southwest (I kid you not). After listening to him talk for 40 minutes about his odd experiences with ufos on his trips to New Mexico, we were more than ready to get out of the car!
We try to go in and out of San Diego obviously, but sometimes LAX is worth it. We are thinking of renting a car here and dropping it off at LAX and taking the airport shuttle in/out. I think that it will be cheaper than parking our car up there for two weeks.
