D-ABVW is already without F and will fly the skies this month. TF and TH will be gone with the end of the summer 14 schedule. Starting end November the 12 remaining 744 will have their old C and F removed and new C and E installed in 6 months, with each refit taking 32-48 days at two sites. So sometime in May June you will no longer see F in 744.
