ADOPT works great. If senior mgmt made an effort to ensure that it operated properly!
Bidding lines stinks in comparison because the pilots lose flexibilty - especially in top months. If they can screw up adopt they can screw up lines so that NO one is happy.
The current system of rotating bids works well and certainly keeps the company happy. Look at the sick days of jr pilots at straight seniority company's as proof. After a while they simply give up and call in sick. With EK slowing it growth rate there will be more pilots at the bottom for a longer a time.
Regardless of the system used the company has to step in and ensure it runs correctly.
