The Airfix 1/144 Airbus A300, was as far as I know, the last Airfix airliner until 2004''s 1/72 Concorde. Jessica Cooper reviews this 1974 release.

Thanks!

I have to issue a correction. The DACO issue does not contain a decal; I was confusing it with the 737s, which have a superb detail sheet included in the kit. Daco's webpage says that a TNT markings are scheduled. I am confident that they will be of Daco's usual standard.

I have another correction for you.. Heller released a 1/125th Airbus A-300 many moons ago. I have one in my stash with TAA decals for it. One day I may get to build it.
Cheers

1/125 isn't real airliner scale

Actually the Heller 1/125 kits are pretty nice if you can live with square windows and an "adventurous" parts breakdown. They're impressive when they're finished, being a fair bit larger than 1/144 .
