Until recently, I would pay around $100 extra on DL for short trips (or flights without an FC cabin) and around $200 for longer domestic trips with FC cabins. However, my loyalty for DL is waning* and now, decisions are on a case-by-case basis, with cost and flight times being equally considered.
Also, when there is such a price discrepancy among carriers, I'll look at nearby departure cities (for example, FNT).
*Two reasons: Inability to redeem award itineraries at low mileage levels and poor international SWU program.
