Carbon offsets are just donations to environmental groups. There's nothing bad about either taking flights or making donations, but it's wrong in the "factually incorrect" sense to think that if you pick the right amounts to donate to the right groups you can make your flight environmentally friendly. It's like buying a "local business" offset every time you shop at Walmart - you can just do it if you want to or don't do it if you don't.
