Without knowing individual circumstances, my order of choice would be:
1. EK380
2. QR787
3. Anything else
4. EK777
Quality of life on the EK777, read any of the hundreds of other threads!
Time to command on EK777, hm let’s see..
The B777 fleet expansion is over so you’re looking at attrition alone. The current rate is about 100 skippers per year leaving/retiring with 1300 skippers in total so you do the math. The 777x will replace old ER according to fleet management. The saving grace could be introduction of the 787 IF they do mixed fleet flying but probably not
So basically, tell EK you’d like 380 only. If that’s not available, go with QR
