When a necessary service is pushed towards being unprofitable / breakeven due to "free market pressures", it probably should have some kind of backstop to ensure the service doesn't completely fold - because it is necessary. I think the suggestion to treat it like a utility was trying to emphasize this.
I'd also feel similar I'd my primary water, electricity, or internet provider was on the brink of failing due to "free market pressures".
Consumer air travel is not a necessary service, though.
