Wandering around the airport before the flight should help keep your DD occupied for a while. My kids enjoy watching the planes coming & going as well. We also packed a backpack for each of the kids with various activities for the flights going to & from, etc. They included the Crayola Color Wonder markers & coloring books (they only color on the special paper - great for traveling), some snacks, and any other little things that would keep them busy. Little notebooks & pens, some stickers to put on paper, etc. Oh, I had also found them each a Disney themed book where they had to search a page for several different things/characters. DD had Tinkerbell and DS had Pixar movies. It was great!! And they enjoyed finding some special and new items. You can find some great & inexpensive notebooks, pens, etc in the $1 sections at Michaels & Target.
