Virgin America and Alaska are like polar opposites. Alaska are a very bland get you from A to B type airline with shabby A/C interiors that have horrid looking brown carpeted bulkheads (well all the Alaska A/C I've flown on have been anyway).
The WiFi is staying apparently as most Alaska aircraft already have it as both airlines use the GoGo system. The ground to air system is supposed to be getting replaced with a satellite system though.
I guess
the #VXsafetydance will be going as well.
Whilst VX are good, I've found they have been getting very expensive compared to DL or UA.
