Years later when I started traveling for work midweek transcons in coach were nearly $2000 round trip The idea of paying for first was beyond my comprehension.
The cost of coach trips has come down, and in percentage terms the cost of flying first has come down even more. Part of that is a change in airline pricing philosophy, and part is a change in technology. Instead of just having full fare first class and possibly a discount fare bucket, airlines can price first as a specific upcharge to the prevailing coach rate.
That’s helped them sell more seats up front — Delta sells about 60% of its first class seats, American is closer to 50%. It used to be more like one in ten.
