At my last Council meeting, we were told a much improved PBS interface was coming this spring. So, cross your fingers. I don't think 90 hour lines are going to last past this summer, and the return of the PW 777s over the next few months should help take a load off. If you read the SSC update from yesterday's MEC update, the 737 fleet has had pretty eye popping cancellation numbers the last few months. I think mgmt knows they need to shift flying elsewhere as it comes back on line.
I bid WB a couple months back because I decided I needed a slower pace for couple of years (I'll be a LH).
Here is something that is maybe counterintuitive and didn't occur to me for a few years - bid longer/fewer workblocks + shorter trips. Shorter trips are much easier to drop and trade. I rarely am able to drop a trip of 3+ days. Also, make sure you look at Line Construction Floor and Line Construction Average when putting in your bid and bid for a lower credit line if possible (one that won't cause your whole bid group to fail).
Get awarded back to back one days? Look to trade them both for a two day ending in a DH that you can fake. It is not unusual at all for me to do exactly this. You need to set up trip notifications in Crew Companion as well if you haven't already (not CCS, those notifications suck). You can customize alerts from Crew Companion for trips that you might actually be interested in, such as ones with lots of soft time or laying over in your hometown. Oh, and if you can figure out who the LCAs are in your base, try to bid or trade into trips with them and maybe you'll get bought out occasionally.
Anyways, apologies for wasting your time if you don't already know this. In "normal" times I was averaging about 90-100 hours of pay a month but only about 45-50 of it was hard time. I've been earning much more lately, but working more too. YMMV, good luck.
