From DiamondZ,
4. Temporary Vacancy Awards
a. A temporary vacancy(ies) shall be awarded in order of seniority to pilots
who:
i. are currently qualified in and currently hold a permanent position in the
crew status in which the temporary vacancy exists at a base(s)
specified by the Company as provided in Section 24.B.2.b.; and
ii. have requested that temporary vacancy on their standing bid.
d. A temporary vacancy may be utilized only at an existing non-FDA domicile.
Two very important differences from the LOA STV provision. If you're going to equate the two, make sure you understand those differences.
