OK deep breaths....HELP!!!!

Our flight has been delayed and is not due to leave till 9pm (I hate Jetstar!!). Lucas is normally in bed at 7.30pm and i am so stressed! He is going to be feral! I dont know what to do.....there is nothing i can do! Do i bath and bottle before we leave for the airport? Wait till we get to the airport? Top up when we get to Noosa? We wont get into our accommodation till midnight. Oh jeepers.....
