"The whole industry is going self-service," said Robert Mann, an airline consultant and president of R.W. Mann & Co. "The fact that Spirit might be the one to try to essentially eliminate customer contact, or at least customer contact with a human being, is not surprising. They are among the most-aggressive in this area."
Spirit already charges more fees than most airlines. Assigned seats will cost passengers $8 to $20 extra, and that includes the dreaded middle seat. Coke, Sprite or water run an extra $3. The airline's philosophy is to keep its base fares low and then let passengers decide which added services they want to pay for.
But there is only so far that Spirit's CEO said he is willing to go. While Ryanair has talked about charging to use the bathroom mid-flight, Baldanza ruled out such a fee on his airline.
Nor would he consider selling standing-room only, or bar-stool like spaces on a flight, as Ryanair's CEO Michael O'Leary has boldly proposed.
"We would not consider charging for bathrooms," Baldanza told ABC News. "We are not seriously and I don't believe Ryanair is seriously looking at standing up on planes. There are plenty of federal regulators here and in Europe who would have plenty to say about standing up."
Baldanza said he's not morally opposed to charging for bathrooms but takes the approach that it's essential to taking the trip, it's included in your base fare. Only if something is an optional service does Baldanza believe it's reasonable to charge an extra fee.
"We just don't think of bathrooms as being an option thing," he said. "When you have to go, you have to go."
