After seeing a lot of enhancements that airlines have done in the past few years, in particular, business and first class seats, does anyone know how much each seat costs?

I know CO's new BusinessFirst seat costs $26,000 each. (Well, okay, probably including installation costs.)

I know that it cost BA $1 million/plane to install the new first class (way back when). So, that's about $80,000/seat. (Probably including installation costs.)

The seat in a fighter jet costs $80,000 because of the ejection system.

I'm curious about those antiquated coach seats that most airlines use, in particular, the ones with TVs and the ones without TVs.
