With more than 24, I was told by phone agent I would have to rebook with a $75 change fee (per person) to upgrade at a $220 additional cost for MCS. With less than 24 I was offered $220 to go to MCS from LAX to FLL. On the phone, the agent said at less than 6 hours it would be $270 for first. Since we were sleeping LAX-FLL we skipped the upgrade.

On the return FLL-SFO during the day, we upped it as we were awake to enjoy food and movies.
