I can't quite access what I read at the moment, but I may have misunderstood (my summary of what was said was from memory). I'm now starting to doubt myself, but I'll check again when I have the chance.
Personally, I found what I read to be odd, and expected branding to disappear with planes ending up much like the ATR's.
However, if Skywest was to adopt the livery of VA, I wonder how long it would take to have all the aircraft painted. Virgin aren't exactly accelerating through their Virgin Blue repaints.
As of know, If I'm not mistaken, only ZPR and ZPT of the E190's are in new livery (of which neither ever were in Virgin Blue livery). Of the 737's, the -YF*, -YV
* and -YI* series are in new livery (all delivered post-transition or in white), so is VH
-VUZ and VH
-VUY (never were in the old livery). The only 2 737's I can think of from the top of my head that have been painted from the old to new are VH
-VUF and VH
-VUG. And of course the A330's are in the new livery. Now, if I'm correct, that is a very slow transition, which I find odd, seeing as VA want to leave the LCC image that was DY
