A bit of misinformation in here concerning direct or near entry captains.

In ORD, CA's on the 145 can hold a line after about 1 year and 10 months and DFW reserve after about 1 year, looking at the current list. ORD seems to be the junior base at the moment but we all know that can change with the next bid.

175 can be held as reserve line after about 14-16 months in ORD.
DFW, you are looking at more than 2 years to get a 175 reserve line.

Of course this all can change as well the more 175's we get.
