Redundancy alert: future plans.
Can plans be anything else? Yes, I know, sometimes plans don't work out. But the context should make that clear.
If someone says "I have a plan," you don't assume they're talking about a plan for a day ago, or a week ago. That person has a plan for something coming up. This stems from people's insane desire to clutter up writing with useless words. If writing exists to communicate, why add filler? No defense exists.
I don't want to harp on trifles. But this isn't a trifle. It's common sense.
