Hi Gill, 
This week, I have learnt something new.  
When you paid a deposit, you should have received a confirmation invoice within a couple of days. A second invoice is only issued if there are changes to the holiday which affects the ATOL certificate or you request one. If you would like me to arrange to have a new invoice sent to you, please let me know. 
Flights are currently listed as  
Depart Gatwick 08:00hrs 
Arrive Gatwick: 12:50hrs 
These are provisional times and subject to change, and would be confirmed in your final documents. 
Kindest regards, 
Julia
