They then got lease 777s and again, have started getting rid of them before 787 issues fully resolved. All the talk now about getting 787 10s and getting rid of the 777 200 in 2022. Yes, new GE engines but who’s not to say they’ll have issues. Wouldn’t be releasing one more perfectly reliable 777 until all 787s run seamlessly. Company and accountants being tight! All they see are fuel savings re fleet composition. Not prepared to have an extra cent on the bottom line re 777s over 787 a moment longer than they have to. Customers and brand the losers. Meanwhile managers get bonuses
As you said, the goalposts keep moving.
The issues with the Package C engines, for the most part, is resolved/managed. The current issues with the TEN engines (which effect 4 of our 787's) was only communicated by RR a week ago (at best). And lets not forget, the TEN engines were touted by RR to be the fix for the Pack C issues. In reality, they're even worse.
Could the GE's have issues? Of course. Could the the Trent 800 engines (on our 772's) also have unknown issues? Hard to say. Does a 737-800 have cracked pickle forks?! Perhaps all 737 NG operators should have held onto their Classic 300/400's for an extra decade "just in case". There comes a point when holding onto old frames "just in case" is simply not viable. Especially when the Engine manufacturer sells you (and ever other Airlines) a lie that the newer version of an Engine has resolved the issues at hand. I guarantee,
every 787 operator worldwide would happily operate a fleet of old, reliable 767's with the benefit of hindsight.
The lease 772's from Singapore got parked up in the desert. We still have the -300 lease from EVA. I doubt any 772's will get parked up anytime soon. With 8 orders for 787-10's and another 12 options... there's enough orders to start replacing RR 789's before retiring the 772's.
