You bet they Do. The company constantly runs practice bids to see what people are planning, especially before a new planned domicile ( Like LAX a few years back) or preceding a New vacancy Bid..........like is rumored next month.

The bean counters are all over this............except it is ficticious info..................just watch how the practice bids change form the final real bid.........................

Tony C just may have something........................Everyone BID MEM 737 Cap and MEM 737 FO as your back up................................
Until the seconds before the actual Bid closes
