My daughter is an employee of Delta (not a pilot) and I bugged her for a long time if and when I could get into a simulator. They have about six lined up in a huge training facility starting with the MD-88 and working up in size to the 777-LR (long range). When Delta is not using the simulators for actual pilot training, if someone has time they will allow you to get into the simulators and fly. I am not if this is common practice, so I consider myself very lucky. Our instructor was actually an IT person sitting in the observers seat setting up every possible scenario one can imagine. I doubt they can simulate both wings falling off though!
