Not very good actually. The AA regionals (and many others as well) have had company paid parking at your home airport (if commuting) or in base if driving for decades. You don't even turn in receipts, they send your parking place a company voucher with your ID number, and credit card billing authorization. Once set up, you never worry about parking again.

Sounds like Frontier could use more than just rate improvements...... something for your NC to use at the table perhaps.
