Recall that, if you wish to use PB Days to drop a rotation(s) on which there is insufficient
reserve coverage and you do not wish to use your APD or an IVD, you may submit both a PB
Day and a PD request for the same rotation(s). If another pilot subsequently is awarded the
resulting Qualified Personal Drop (QPD) rotation, your PD request will be awarded. You can
then use the SmartSheet on the Crew Resources/Scheduling page in DeltaNet to request that
a PB Day(s) be placed over the dropped rotation(s).
