(CNN) -- No advanced seat selection, no changes or refunds. Sound like Spirit Airlines? Nope. It's Delta Air Lines' new "Basic Economy" fare, part of the airline's new five-fare class of pricing starting March 1. No longer content to just offer first-class and coach-cabin seating, Delta is splitting its aircraft into five fare classes. Travelers who want more than "Basic Economy" will pay more -- Delta's not saying yet how much more -- although that's already the reality for many travelers. Passengers who are willing to pay to change their flights and check their bags -- so-called ancillary fees -- helped 26 passenger U.S. airlines turn a net profit of $12.7 billion in 2013, up from a profit of $98 million in 2012.
