Good morning Jackie,
Thanks for getting in touch, sorry you haven't yet been notified of your flight times, I'll take a look into this, you should have been advised at the time of booking. Happy to pass on the flight times now though, you will depart Heathrow at 13:10, landing at 15:30. Return flight times are depart at 12:25 German time and land at Heathrow at 13:00 UK time.
I hope this helps,
Kindest,
Ben
