That calculus might work for you, but doesn't really apply to this flight.
I have looked around online at the Norwegian website - delays like this seem to be few and far between.
So, going from the SF Bay Area to BCN - the shortest non-Norwegian (or Level, another LCC) is 14 hours on Air France. Norwegian is 11 hours non-stop. So, most of the time you will save at least 6 hours of flying time on a round-trip to BCN from the Bay Area by flying Norwegian or Level. I might be willing to pay MORE for that than the slower Air France option.

That's why if the prices with a LCC are just 25% cheaper than a legacy carrier, I wouldn't book it. But if they are 50%+ cheaper (which they frequently are) I'll book them and take the risk.
