+1. They lost me, unless circumstances totally force me to take them (and probably credit to some other program). There were huge dips due to 9/11, SARS and the great recession in the aughts (just to think of three).
Now Spirit is going to add 9 more routes to the 5 or 6 it already has out of ATL, despite DL and WN having bigger operations. So leisure travelers will have WN with the free bags, NK with the charge-for-everything but much lower base fares, and DL for....what? Arguably NK and WN both have more-rewarding FF prgrams for low-rev people now, especially if u can tap into the credit-card-linked ones on NK. With DL a $200 ticket now gets 1,000-1,400 miles, so you'd need 18-25 for a 25K award that probably won't have availability anyway.
