It's all over the place and my van time is in a little bit, but here goes: (caveat, I don't have the rules in front of me, so just giving you what I see when I bid)

There will be a couple lines with a bunch of turns or 2-days. I think I saw a line with 9 turns and a 3 day out of LAS for DEC.

We generally have pure pm or am lines. Blank lines (vacation/military/sick drop) can and usually are mixed, may even have a reserve pairing mixed in for good measure. For whatever reason, our PMs tend to turn am through ORF. Not sure why, may have something to do with the wallpaper on the ceiling. Sorry, internal joke. However, these trips tend to be commutable for our PMers, gotta love that smokey Waffle House!

AM lines generally pay more but have more time off. The best lines with max days off are always AMs. PMs can be commutable though.

Dec max days off is 20 days off, am line. 19 for the pms. LAS Dec avg pay 97 tfp / 17.8 days off.

Usually your lines are 3 on / 4 off or 4 on / 3 off. The latter usually leads to a chunk of time off on the front or back side of the month. These lines always start and end on the same days, good if you have a hard schedule at home - kiddos, wifey works, .... Sometimes you have a 2-day or turn tossed into the above lines. Just means you have to give it away or trade it.

I say "usually" above, because you will see about a dozen lines with weeks off throughout the month. Or mixed 3-, 4- turn 2-day lines. These lines are usually minimal and are probably made to meet contractual requirements.

Trip trade / give-away is great, ELITT is good for about a minute after it opens, then again about 2 in the morning when all the pmers get to the hotel that night.

Hope you get a better feel. gotta go.
