Yes, they will pay for parking or reimburse you you to a certain amount.

As for travel benefits,
AA $75 for you, $50 for her
UA $50 for you, $50 for her
DL $50 for you, the way it's worded, I'm not sure if passriders are included in that $50 or not. If you do pay for each rider, they are $50 as well. However Delta I have been told is no longer charging for flight benefits, though they have not officially made the change yet.
