I surely get that VX has its work cut out for it indeed!
However, it's been my experience on a few key routes (SFO-BOS, JFK, PHL AND WAS) their F class has been much more civil.
Maybe it's the fact that folks that want to pay for the upgrade to F and just the experience of the flight aren't like what I've experienced with UA in the least bit. Sure, there are those that board that have boarded some of my flights in F with entitlements of storing their bags in F when they are in Y. But I've seen the FA remove the bags and inform folks that they can't come to the forward cabin for the restroom too!
There are those here in SFO that want to support VX as the hometown airline regardless of the class of service they are traveling in, but it's just a matter of time before circumstances make us think otherwise as the bell might be tolling for VX!
Hoping that VX hangs in there for sure! But until then, keep up the great trend setting mode VX!
