If they are going to either of the Chicago airports early in the morning maybe the FIL doesn't like to drive in horrible rush hour traffic! Chicago traffic can be terrible and maybe getting older her doesn't feel comfortable. Also for an early morning flight out of Chicago you have to allow easily an extra hour cause you never know when you might be in a parking lot on any of the expressways.
I have left my car at both Chicago airports without any problems.
When we plan vacation I always plan on paying for either staying overnight and leaving the car or long term parking and then if someone offres and actually comes thru great if not I have already planned for it.
I'm also in the camp that I would never be able to go away on vacation if I had so little in reserve that having to pay for parking was a deal killer.
Just be very happy he told you 6 weeks away he could have told you 6 hours away!
