One thing I'd like to see on the long haul Hawaii flights is for UA to brand them as Polaris flights. AA is now branding their long haul flights to HI as Flagship Business now (including Flagship Lounge access when open and DL brands them as Delta One. , also with lounge access). UA is somewhat non competitive by simply branding them as First without any lounge access for the premium passengers.
Being in Houston, I'll of course still fly UA, but as one who is willing to pay for premium leisure travel, I'd gladly pay a few hundred more to include Polaris Lounge access to match AA
