Well at least they will have had plenty of time to learn from Norwegian’s foray into the US market.
Lesson number 1 is that without CPDLC sat comm you’ll be stuck at FL340 or less and even with it you’ll struggle to get high enough west bound to get above the jet stream peak winds due fuel load, 2. you are a slow aircraft at .78 or .79 so you won’t get optimum FL’s even if you could climb there. 3. fatigue induced crew sickness is a real problem to sort out 3500 miles away without local US based crews on hand. 4. going non ETOPS in 1 leg is close to impossible with a viable payload.
