This was inevitable
The other news is...the mil charters will be the "proving flights" for more extensive TATL ops with this machine.
Soon we'll see CO attempt to operate the 739ER on short TATL sectors in revenue service, just like we asked them about at the '07 DO. For example, EWR-SNN is certainly possible with appropriate ETOPS qualification.
Anything to free up 752s and push them to sub for EU-bound 764s.
