Is there a shuttle or service available when dropping off a car at 5:00 am to get to the airport for a flight? Is there acharge for the service or provided by Hertz to its costumers?

At enormous expense sf at their SFO built an elevated light rail like Disneyland, from the "donut" terminal to the new N.garage, to get rid of diesel buses and well paid bus drivers! They could have gone to just LNG buses. It's like building BART to SF when so much safer and better Caltrain already existed; You can wish BART was world-class all you want, but it is Not. Such a Giant waste of taxpayer money!

Air Train and shuttle operates free of charge..when I was there airtrain got some issue, so shuttle was running

The air train to SFO operates 24/7.. No charges at all.

Hertz is open 24 hours, there is always the train or the bus from and to hertz. No charges. At the arrival we got the bus from airport to hertz ( look for the bus which goes to rental cars) and at the departure there was the train from hertz to airport. It usually runs, but if it doesn t, the bus is provided
