Going to be going flying to MD a few times this year for work.  My folks place is only a few hours away in PA and I was thinking about picking up a few of my guns and flying back with them.  Is there anything I should be aware of?  If I'm not mistaken my AR's and AK's are all no-no's but everything else should be fine.  I checked the banned list of firearms in the tacked thread, and I don't own anything on there other than AR's and AK's.

I only ask because I was going to do this last year but was flying in and out of CT and found out it would have been a felony for me to bring my guns there just to fly out with them.
