I believe this may have been brought up before however, I believe it is important to address this again. The JetBlue A320 livery is missing text on the inner sides of the engines, and the winglets should be grey on the inside instead of blue.
I also noticed, but considering how minor of inconveniences this is, it’s quite unlikely action will be taken.
Some of their a320s do have blue painted winglets actually, but the majority don’t. As a JetBlue fan I agree there should be this fix!
Noted internally.
Thanks!
