the point is -- had the OP known that the F seat was broken, he would not have taken the upgrade. clearly the OP feels the marginal addition of personal space and service is by no means worth the trade of a working J seat.

a cost benefit analysis with which i completely agree.

when CX requests a pax to accept a change in the specs of their product (a change in the guise of a so-called upgrade) one would hope CX takes the care to ensure the change is at least of comparable value.

by not doing so, this is no different from the many bait and switch stories you hear online and off.
