I've flown JB mint on a trans con and I have to say it was excellent. Honestly rivaled Delta One on the 330. Mint was a little cleaner and had better food and drinks also. Plus happ(ier) FAs. I'm sure their trans Atlantic service is top notch, but at the end of the day it's all about the numbers. We'll see if they can do it profitably and hurt us once business travel and international travel really opens back up.
