Many Thanks for your reply! Where did you get this info ? I see in the JP
Fleets book that FF
seems to be available. However, Boeing doesn't always allocate the number in alphabetic order; VN
only recently get their first direct purchase Boeing aircraft and was allocated 6K, well after Linjeflyg that got 9D in 1990 when they got their 737-500s.
Fleets book list other codes as not assigned although I'm not sure how complete their list is eg they miss the listing for VN
Boeing 777s flown: UA, TG, KE, BA, CX, NH, JD, JL, CZ, SQ, EK, NG, CO, AF, SV, KU, DL, AA, MH, OZ, CA, MS, SU, LY, RG, PE, AZ, KL, VN, PK, EY, NZ, AM, BR, AC, DT, UU, OS, AI, 9W, KQ, QR, VA, JJ, ET, TK, PR, BG, T5, CI, MU and LX.. Further to fly.. LH 777
