flying with a newborn

Kiff
So my husband and I are planning a family trip in August to see my family in Colorado. August is the best time for everyone it seems. I'm just nervous because our baby will be about 6 weeks old. Has anyone ever flown with a newborn? Not only that but being in a different state when the baby is still so new, not sleeping during the night.. idk. I'm just trying to see the best of the situation but it seems like it's going to be a lot of work.
