Can't answer the question because none of us know what $119 x 4 means to you. If $476 is what your bar tab after work, it's worth it. If it's the delinquency which will cause your mortgage to be foreclosed it's not. Only you know where you fit inbetween.
For what it's worth, the flight is blocked at approx. 3:10 (you may not have considered the time difference) and as a rough gauge, the difference between the generally available lowest fare in Y ($222) and fare which books directly into FC is approx. $170. If you subtract what you paid per ticket from $392, you will have a # to compare to your $119 UG offer. Doesn't tell you that it's good value and it's an approximation.
Me, I would jump at this. But, that's me.
