First time flying with a baby

Hey everyone! I am a first time mom flying with my 4 month old to an international destination. Our flight is about 14 hours. I am flying with my husband and our baby. We have a seat for our baby and are bringing her car seat to secure in her seat. Our flight is over night from about midnight to 2pm the next day. <br><br>How should I keep her occupied during the flight? We are planning on having her sleep most of the flight but how should I keep her occupied when she's awake? The flight doesn't offer bassinet seats.
