Airport fast-charging?

While the suggestion for airports to provide sufficient slow-charging outlets in long-term car-parking is one possible solution, it neglects to acknowledge the cost to the airport operator versus the relatively low potential return. Even if a dedicated slow-charger could be installed for $3k, it makes for a poor business case if the revenue limit is maybe $5/day before operating costs are factored in (note that this is in addition to the costs/revenues of an ICE parking spot). It also fails to take into account the opportunity costs of having dedicated EV parking that may be underutilised.

A 50 kW fast-charger can provide around 30 miles of range in 15 min, be managed thru an on-line reservation system, occupies the equivalent land area as maybe 3 normal parking-bays at most while being able to service 3 users per hour, and enables a premium to be charged for the service ($10 for 15mins?). The capital costs may be significantly higher but grants and equipment cost reductions are making it viable for high traffic locations such as airports, and less land area is required.

Any thoughts?...
