Oh, for sure! You would need a significant amount of investment capital to build out and get running before bringing in revenue.

It also smooths out your revenue a little bit and helps to pay the expense of building and maintaining your own airports.

Do a club model. Monthly/annual fees grants access to:

* Per flight discounts
* Access to the loungeport and its amenities, even when not flying
* Discounts on stays at the hotel, car rentals, etc.
* Discounts at partner businesses, the way airlines partner with other companies for their milage programs

You could do it like Costco where membership is mandatory, or like Disney where club memberships are optional extras.
