I am looking at flights from SLC to SYD on Delta and I am confused. When I look at the seat chart for the long flight they list Business Elite, Premium Economy and Economy as the cabins. But in the pricing they list Economy and then First/Business. I am trying to figure out what the pricing would be for the Premium Economy. In the seat chart it looks like seats the size of Business Elite, then they get smaller in economy. Is it safe to assume Business Elite = First Class and Premium Economy = Business class?? I am annoyed that they don't have uniform names all across the board. Why do they name a cabin Premium Economy when they don't have that term in their pricing??
