Flight times are always being tweaked every schedule change.
It happens to me a lot too. We have to recognize that frerquency of flights and equipment changes are going to keep happening while the airline industry struggles to make a profit.
I would just switch the ticket to the best time you can.
NWA has no obligation to comp you anything for changing the schedule. This is a "nuisance complaint" without any solid basis.
