Delta Air Lines gets rid of unpopular type of seats
Passengers may not like all the changes the airline has made to how it sells seats.

Remember when booking a flight meant two choices — first class or coach? And seats in both classes came with "perks" like actually knowing where on the plane you were going to sit?
Those days are long gone, and now you practically need a special dictionary to navigate all the different terms that airlines have for various seating categories and classes.
