I just flew with a 25 year F/O (777) who lives in DFW and commutes to ATL, he said the standby list to get to ATL is always about 40+ commuting employees long. He buys 'fly confirmed for less' tickets to get to/from work if need be, said it's about $120 each way.

DFW was at one time nearly as big a base as ATL, pilot wise, and there are lots of senior F/A's commuting to ATL from there too. Every guy I know who does that commute says it's a nightmare. You will be competing against some very senior F/A's and pilots to get on any Delta jet going to ATL.

I have not spoken with anyone who commutes DFW to SLC, DTW or MSP but one guy I know who does DFW-LAX uses American's jumpseats more than Delta's.
