A semi-hypothetical question.

Given that a First Class seat is worth 'something more', how much more
is it worth to you on:


a 5 hour flight?
10 hours?
15 hours?

A seat twice the size is worth twice the fare.

Well technically the seat is 1.5x the size, but the legroom is also
about 1.4x the amount.

The airlines price those seats at varying multiples of the coach fare. I
recently bought a ticket from SFO to LAS and the coach fare was $138 r/t
and the first class fare was $600 r/t. At the airport they offered me a
first class upgrade for $50. The plane was almost empty, and it was less
than a 90 minute flight, so it wasn't worth it.
