NWA had 150% for everything over 80 hours. There were also "designated" premium trips in open time that paid 150% regardless of your total credit, but if you were over 80, the two multipliers stacked, and the result was 225%. The advantage was that you could pick up premium flying WAY out ahead of time, know your schedule and plan your commute, and you never had to ever obsess over the phone, waiting for it to ping and then make a mad dash for the door. But there was a fairly restrictive credit cap that you could only exceed in certain circumstances. Open time ran once per day, at midnight, and anyone over the scheduled monthly max (a functional equivilent of the ALV) went behind everyone else who wasn't. Inverse assignemnts (called involuntary call outs) were extremely restricted. No real reroute protection/pay. No way to simply drop days. You could trade from longer trips to shorter trips, but if you fell below a certain level (monthly max -7, I think) you had to sit days of pseudo reserve at the end of the month.

There was no functional way for reserves to make more, other than to fly more. In fact, block and reserve were separate bid statuses as permament positions. You couldn't simply go back and forth. That said, everything was very commuter friendly, and there were no mad dashes to the airport because of a short notice GS assignment. Pre-Whitlow, reserve was 24 hour short call every reserve day.

Reserve work rules weren't even an after thought. The mantra was that reserve sucks, so maximumize the number of line holders, and if you don't like reserve, don't bid it, and if too junior, get more senior, and if you can't do that, well, sucks to be you.

Pre-PBS was line bidding. Everyone had a desginated "5 minute window" where you could call in your bid to the scheduling analyst. You ran your choices past them, and they'd let you know what was left and who the captain/FO/SO was also on that line. Conflicts dropped. You could slide your vacation backwards or forwards 3 days, so running that exercise with 100 or so lines to get the opimum result was a chore. You could also put a line together out of open time (which populated as time dropped out due to conflicts).

If you happened to be in MSP during your window, you could bid in person, which was a real blast from the past. You went into this room at the old Building F. It was set up like some local commodities trader, and had greaseboards with line numbers for each seat, and 5 or 6 schedule analysts arranged in kind of a horseshoe arrangement. As people bid, the boxes would get filled in, and you could work with the analyst directly. You had exacty 5 minutes, so if someone needed more complicated information, there was a "buddy phone" that if you were there, you were supposed to pick up, and you could help the person on the other end by giving them info off the boards.

If you weren't available during that time, you left your bid in the computer, and the company simply assigned you the line your seniority could hold.

In some ways, NWA was better, but scheduling work rules wasn't one of them.
