Unfortunately it makes perfect sense for SWA. If MCO is scheduled (at this time) to open at 6 PM then SWA would need to schedule crews, planes, and commit to a scheduled set of flights that might not actually happen. It would be a very narrow window.Interesting since Southwest cancelled my flight from Washington DC to MCO arriving Thursday evening at 9:50pm.
In their Scheduling system it just makes more sense to skip MCO tomorrow and restart their schedule on Friday.
