Basically the same. All DH's in bid pack must be commercial tickets of which you can deviate, collect the miles (full Y fare), or bank 65% of the cost index of that DH for use on other commercial flights. You can't use that bank for personal use. How much you DH depends a little bit on fleet and what you choose to bid. We have some commuter protection language that protects from disciplinary action but you are not pay protected. We have an online JS booking system for company flights that allows you to book 13 days out. It's first come first serve and you are guaranteed that seat if you book it unless the company has a last minute DH. It's rare to get bumped but it does happen (ANC SDF for example).
