Go to
www.expressjetpilots.com/the-pipe and go to the crash pad section. You will find a couple of postings for crashpads in ONT. Most cost between 200 and 250 a month. I would even offer a spot at ours but, we are full. There are a couple of postings in the crew room in ONT. Some are shared houses, others apartments. As a side note you will need to have a car unless you plan on staying at a hotel close to the airport. The public transportation is fine but not a lot to do without a car to get around. If so the Red roof Inn is your best bet. If you are planning on living down here then you will have some additional options. If you need any additional info post it on here or PM me.
