(CNN) — Coach or first class–it’s a common decision air travelers have to make.

At Delta, you’re about to have a little more choice. That’s because the airline is splitting its aircraft into five classes.

Starting in March, Delta will begin offering three main cabin options and two high-end options.

At the low end of the spectrum is “basic economy”–the bare-bones coach fares.

For more money, you can upgrade to options that include seat selection and dedicated overhead bin space.

Delta hasn’t said what the pricing difference will be for the classes. And it’s still unclear if the bare-bones option will be cheaper than coach tickets right now or if customers will get less for the same price.
