While I myself also prefer the VX interior, AS isn’t really doing their part and maintaining the older interiors. Both of my flights on the VX interiors (N843VA and N526VA) last year had numerous problems with the first class seats. While I’d imagine the select A321neos with the newer VX first class seats likely do not have this problem, it’s not likely I’ll be on one. My flights to Vegas will be on an A319 and A320 in economy, so I’ll have the chance to see what VX economy is like.
