There are still a few Airlines/planes that have yet to be used in daily specials/events:
-Air New Zealand A21NX Black Livery
-Airbus A320 house livery
-Boeing 747-400 House livery
-Flyboys 787-900 Orca livery
-Italian Air Force A319
-Oman Air A319
- Royal Air Force Oman-RAFO A320
-USAF 757-200
When will these long awaited planes be playable?
There are a couple more:
The Comac’s and Delta B763 (although recently added)
JSX E135 (2x) and E145 (or i might have missed them 
)
The Air New Zealand A21NX has appeared though, as i’ve already caught that one.
Delta B763 Habitat for Humanity and all the JSX ERJs have appeared, Delta was December 21st at SCL and JSX the day before at MSY.
Italian Air Force A319 is an old one and has definitely been used. I have it unlocked in my WoApedia.
Think it got removed at some point as I remember seeing it at BRI - but it’s long gone.
Similar thing happened with the Czech Air Force A319.
Both of those were obtainable to my knowledge before the woapedia was readded, but haven’t appeared since. So if you had the contract or an event saved then you could have gotten them, but otherwise you couldn’t have.
These are the ones that I’m missing. Some of the new liveries have not been appeared yet. I don’t know when I missed the red tail concorde, although I play the game daily for the last 2 or 2,5 years. 
Many thanks. Wonder what I was thinking that day…
It’s available at SYD today!
And also missing Thai Airways B744 Royal Barge livery
That definitely appeared before!
When?

The below thread has a clear list of when (most) liveries appeared
Me too. It’s appeared a few times in the past but not for the better part of a year.
Where you guys get the large cargo planes of UPS Europe?
I think but don’t quote me that they can be found in Germany from LHR
