Whoa, I suspected EI-DCR too in my reconstruction!Then maybe this one

found 2004-12-19 SS0870 ORY TNR ---- ---- fakepcy F-GSEX #9077Thank you so much! A few more additional flights if it's okay with you:
2004-12-19 SS0910 ORY TNR ---- ---- fakepcy ends at RUN
2004-12-26 MK0014 MRU CDG ---- ---- A343 fakepcy
2007-07-22 DS4226 ATH ORY 1350 1620 A319 fakepcy could be a G-EZ tail number using a U2 callsign
2008-12-20 TP0439 ORY LIS 1705 1830 A320 fakepcy
Could you give me a link to OTT? I think there might be some flights I could solve, thanks!
Also, just to confirm for VIE since I solved all but one. The missing AF1239 in 2004 and AF1238 in 2005 if it wasn't a typo could get solved through asking the airport, right? So that I can let the requester know.

Kinda weird because I can't connect these twoThen maybe this one

So I checked it again and it seems that, given the callsigns are correct, the aircraft that flew MRS-STN as FR6539/RYR3FZ was not the same as for STN-MRS FR6538/RYR7JTKinda weird because I can't connect these two
FR6539 MRS-STN 15:13-15:46 3FZ
FR6017 MRS-LIL 19:54-21:30
On FlightStats it only shows FR6538 for STN-MRS, so there is a good chance there were unlisted flights or something. I don't think the callsigns are wrong because EI-DCR flew STN-NYO-STN that morning before FR6539.

Thank you! He gave a correction that he flew MRS-STN on the 2nd since he provided the wrong date. Using the callsigns you deciphered, I was able to solve themSo I checked it again and it seems that, given the callsigns are correct, the aircraft that flew MRS-STN as FR6539/RYR3FZ was not the same as for STN-MRS FR6538/RYR7JT
So maybe there was an aircraft change due to whatever reasons

No need to add these to the list
2006-07-02 MH0156 KUL DXB 0725 1025 fakepcy
2006-10-26 MH6123 DXB KUL 2020 0710 fakepcy
2006-11-22 MH6144 KUL DXB 0545 0840 fakepcy
For some reason, the last two sound like cargo flights? I think there's still hope for their tail numbers since MH6123 originates from AMS to BSL while MH6144 ends at FRA.
