Spirit (and Frontier) are both retrenching. They are reducing their markets served, and adjusting their flying to more flights per day to fewer markets. That prevents the issue of your one flight a day being cancelled and being stuck for another day. Consumers will buy the cheapest fare, assuming they believe it will actually get them there.

Spirit and Frontier merger would fix a lot of the scale issues that each individual airline is dealing with right now.
