When a Flight Attendant requests PTO for a scheduled pairing, but does not have sufficient PTO days remaining to cover each duty period within the pairing, these requests will be awarded by applying a Personal Drop to the remaining duty period(s) provided personal drops are available for the other day(s) of the pairing.
In relation to the removal of a personal drop indicator for an awarded PTO, it's important to keep in mind that Personal Drops granted in conjunction with PTO are not eligible to have the Personal Drop indicator removed.
For more information on Personal Drops being applied to PTO requests, visit the One United Guide located HERE on Flying Together.
