That sounds like a lot of effort though.
The effort is in adding you extra liveries again which doesn't take long. At least it doesn't take long for me because I'm doing it all the time. ;)

Ahhhhh, those were the day my friend......
I don't think I'm quite old enough for those times. But back in those day, it was probably the wealthy, or at least those who were able to save enough (a lot of) money to fly on the airliners. :(
