They will not opt for leap engines. They have very good contracts with PW and if you look back all the new aircraft’s and new engines initially have problems and it takes good time to solve them.
As far as people those who are thinking that Leap engines don’t have any problem is because there are not many leap engines being used and not flying as much as Neos.
Indigo didn’t have much problems for first 12-15 months apart from engines taking time to start. After a while all such problems come up and then manufacturers have to modify parts accrodingly.
So we will have to wait and see for leap engines, if they really have any problems or not.
