4. Conversion Lines

a. A conversion line is a reserve line that has been converted into a secondary line as provided in this paragraph. Conversion lines shall be constructed after the construction of all secondary lines and in seniority order among those pilots submitting for conversion.

b. A pilot's bid may contain a submission for conversion of his reserve line, if awarded.

c. If a pilot submits a line construction worksheet that identifies certain days off to be protected, his reserve line shall not be voluntarily converted unless those days off are protected.

d. A pilot who has submitted for a voluntary conversion line shall contact VIPS within 3 days prior to the commencement of the bid period to determine if his line was converted.

e. Involuntary Conversion Lines

i. The Company may involuntarily assign conversion lines if:

(a) more than 5% of the total CH value of trips from the bid period package exists in open time after construction of voluntary conversion lines, or

(b) there are trips remaining in open time that operate over New Year's Eve and Day, Thanksgiving or Christmas Eve and Day.

ii. Involuntary conversion lines will be assigned until the thresholds established in Section 25.D.4.e.i.(a) and (b) no longer exist.

iii. Pilots shall be selected for such assignment in reverse seniority order. The additional conversion lines shall then be assigned in seniority order among those pilots. The number of reserve lines involuntarily converted may not exceed 50% of the total published reserve lines remaining after voluntary conversions. A pilot whose reserve line has been involuntarily converted shall be notified of the conversion as soon as practical.

f. Conversion lines shall comply with the provisions of Section 25.D.1.b. through D.1.e. (above). If a conversion line cannot reasonably be constructed entirely of trips, it may be constructed of trips and R-days.

g. The assignment of a conversion line may not conflict with a trip that began in the previous month.
