Right now the M88 will give you a commutable line within 2 months. Delta does a pretty good job in my opinion of making commutable trips. Most on both ends and the rest on one end. Also reserve isn't bad because day 1 will always be 10am or later. Then if you bid for your golden days properly you can be off early on the last day if not assigned anything. Combine that with booking the jumpseat and Delta is a lot more commuter friendly than I thought going in.
