So my boss asked me to fly to LAX (or SNA or ONT) this evening for 2 days. I am trying to rent a car and Hertz is completely sold out at LAX, SNA, and ONT. I have business near all 3 airports so I can fly into any of those. I also just checked Avis and they are also sold out. This is weird. I have not been doing business travel for that long but this has never happened before. What do you guys do in these cases? The only companies that have cars are companies I have not heard of or barely heard of.
