sitting in the airport

We are sitting at the airport waiting to board the plan.  The flight to Charlotte should not be bad but I am not looking forward to our 8 hour flight to England, especially since we will be flying over the ocean most of the time.  I'm hoping I will be able to sleep on the plane so that I am awake and energized when we land around 8:00am.  I have never traveled outside of the United States before so I am very excited to travel to England!
