The only problem with that argument is that the people who most need to pick up trips are on Availability every month now, except their reserve months. They have no way of picking up trips bcause the APFA doesn't give a crap about people on Availability since the vaunted SENIOR f/as don't have to fly it.
They don't care that Crew Planning builds the Availability lines such that it is almost impossible to pick up trips on your days off, and since scheduling puts almost no open trips into open time until the day before the trip, there is little to no opportunity to trade with anything--Open Time or HIBOARD. And, only a person of limited intelligence would OE trips on a regular basis. The whole point of flying high time is to get the premium pay for over 70 hours.
I don't know about other bases, but other than the few who drop everything every month (remember, we is a small base), the other trips posted in HIBOARD are put there by f/as with no contact with reality--"want higher time turn than the 7.30 turn they already have; no signin before 1000, must be back by 1800; No #1."

Most of the people trading with Open Time in SLT are lineholders with the crappy lines who trade for better trips--not necessarily more time--if one should accidentally drop into OT.
I hope you are still doing the Flexibility-Shmexibility cheer when all the more junior f/as have either quit or been furloughed, and you are back on reserve. If you think it can't happen, I was talking with a f/a in ops at ORD late last month who is back on reserve for February
for the first time in 22 years. And, I know of at least one very good f/a at St. Louis who is planning to quit if we don't get off availability soon. Let's face it AVBL is nothing more than AAdvantage Gold reserve.
If the APFA would at least push the company to put Availability lines back on the bidsheet where we might have
some control over our schedules, it would be livable. But, we don't know our schedule until the bid runs are complete. The only thing that you can be sure of is that if you have vacation, they will build you an AVBL line that has as many days off during your vacation period as they possibly can so you won't get paid for most of your vacation days--another issue that the APFA doesn't care about.
