It's not really called that. It's actually called "Basic Economy". Think of it as the Freemium model, but for your real life.

So would you? Ever? Are you happy or angry that this exists? Indifferent?The Economist said:So what is basic economy? For frugal travellers, it?s shorthand for giving up some of the few remaining comforts of flying economy. The biggest sacrifice is losing the ability to reserve a seat when booking a flight (so be prepared for a middle seat in the back row). If you are travelling with family or colleagues, forget about sitting together. Passengers flying basic economy also forfeit their right to upgrade their seats and to change or cancel their reservations more than 24 hours after booking.
...
But some people suspect a more nefarious motive: Delta and its rivals are making basic economy so unpleasant that people will pay extra to ?upgrade? to standard economy. Indeed, when you try to book a reservation on Delta?s basic economy, a screen pops up warning you of all the downsides and requiring you to check a box stating ?I agree to the restrictions? before you can proceed.
