I pack and repack weeks in advance...its part of the fun in planning for me.  Because I was flying Allegiant, I decided to limit myself to one bag which they only allow to be 40 lbs.  Got it to 39.9 lbs ...Ready to walk out the door and stuffed all my New England brochures and maps in the bag at the last minute.  Yup 2 lbs over and they nailed me $50 ...so much for my bargain fare! No time to remove paperwork from bag so bit the bullet and paid ...can we say dumb Debbie dumb.
