The fan on the LEAPX 737/8/9 is 66"
The fan on the GTF 32XNEO is 81"

Which one is more efficient?

The re-engined 737 is like a Toyota Yaris with a spoiler and 20" tires, I'm glad DAL didn't bite...

The timing of the current NB order and the timing of end of deliveries makes me thing there is a NEO in DAL's future, not a 737RE...
