Reasons Report Definitions

Potential Reasons

Explanation

Awarded by previous bids: X

X number of pairings match this bid preference and are already awarded by a previous bid.

Awarded for coverage under a different bid

Pairings matching this bid preference are already awarded, and are listed under a different bid preference.

Awarded to senior bidder

Pairings matching this bid preference are already awarded to a bidder with higher seniority than you.

Awarded to senior shadow bidder

Pairings matching this bid preference are already awarded to a shadow bidder with higher seniority than you.

Best Line Before

The N-PBS Scheduler attempts to build a pairing block, but it could not be built using your bid preferences and the criteria set by the Administrators. The N-PBS Scheduler instead moves your next bid group, resulting in this attempt being listed in your Reasons report.

Best Line Before Empty:  No Pairing Awards Possible

The best line before is empty, thus the N-PBS Scheduler could not build a block with the pairings left in the available pairing pool.

Best Line Before Empty:  Available Pairing Credit Insufficient (Line Not Attempted)

The previous pairing completion attempt produces an empty best line before because there is insufficient available pairing credit to build a line so it is not attempted.

Best Line Before Empty: Block Time Limit Insufficient (Line Not Attempted)

The previous pairing completion attempt produces an empty best line before because the N-PBS Scheduler calculates that a crewmember’s Block Time Limit makes it unrealistic to complete a block.

Best Line Before Empty:  SLG Could Not Find Line Including Priority Stack Date

An SLG completion attempt produces an empty best line before because SLG quit early as it is required to include the priority stack date and could not.

Beyond bid limit: X 

X number of additional pairings match this bid preference, but none were awarded because you placed a limit on the bid preference.

Bid denied

This bid preference is denied, and there are pairings on your block that contradict this preference.

Block is complete

This bid preference is not used to build your pairings because your pairings block was already complete before reaching this point.

If a number appears after the “Block is complete” reason, it indicates the number of pairings that matches the bid but are not awarded because your block is already complete. That is, it reached the minimum or threshold credit value.

Buddy cannot take pairing

Your buddy could not be awarded this pairing, so it cannot be awarded to you either.

Could Not Build Complete Line with Pairing

The pairing is available legally but cannot be used because it could not fit into your block and still build a complete block.

Does not help required language coverage

The pairing is required to help with specific language coverage and the pairing does not help with your required language coverage.

Filtered by higher bid: X

X number of pairings matches this bid preference, but are filtered out of the available pairings pool by Avoid Pairings or Prefer Off bid preferences that are higher in your bid.

Followed By sequence not found

No series of pairings are found that match your Followed By bid preferences.

Forgotten 

A Forget instruction is honored, and the N-PBS Scheduler ignores this bid preference.

Honored

This bid preference is used, and there are no pairings on your block that contradict this preference.

Item overlaps with another: X

X number of pairings match this bid preference, but overlapped with something already awarded.

Matching: X

The total number of pairings that match this bid preference.

Maximum Max-Credit bidders Reached

The maximum number of Maximum Credit blocks already awarded.

Maximum Reduced Lower Limit Line Reached

The maximum number of RLL lines awarded to senior bidders.

Minimum Base Layover line condition violated

The minimum base layover line condition is not met with this bid preference, and some layovers are shorter than the minimum time requested.

Maximum Min-Credit bidders Reached

The maximum number of Minimum Credit blocks already awarded.

Needed for Legality

This pairing is awarded from a lower bid preference to honor either a Min Days Off, Min Days On or Pattern Set Condition bid preference.

Not considered

This bid preference is denied, but there are no pairings on your block that contradict this preference.

Not-Considered Below Reduced Lower Cutoff 

You are below the RLL cutoff as defined by the administrator.

Not-Considered Reduced Block

This means that you are defined as a reduced block bidder; reduced block bidders cannot be awarded an RLL block.

Not honored

This bid preference is denied, and there are pairings on your block that contradict this preference.

Not qualified for language

You did not have the language qualification necessary for these pairings.

Not used

This bid preference is not used to build your block; either because your block is already complete or you used a Clear Schedule and Restart bid preference.

No pairings available 

No pairings that meet your Avoid Pairings and TimePrefer Off bid preferences are available to be awarded. This usually occurs  because too many pairings are eliminated from the pairings pool by your Avoid Pairings and TimePrefer Off bid preferences.

Partially honored

This Prefer Off bid preference is used, but there are also pairings on your block that contradict a portion of this preference. If you submit a range of dates that you want to be free of duty, the N-PBS Scheduler may be able to honor part of the range but not all. This results in a partially honored bid preference.

Restricted location

You are not qualified for the locations of the available pairings so your personal profile restricts you from landing in stations in the available pairings.

[Rule violation]

A standard regulatory rule or contract rules for each specific customer based on the union and Federal Aviation Rules prevents this bid preference from being honored. 

Note: The rule is identified in the reason included on your report.

Over maximum credits for period

The pairing would have caused your block to exceed the maximum credit value for the bid period.

Prevents assignment of minimum GDO (Guaranteed Day Off)

The pairing causes your block to contain more than two single Guaranteed Day Offs (GDOs).

Too many above

You are not awarded a reserve block because the number of reserve blocks already awarded to senior bidders exceed your maximum number.

Violates green on green 

The pairing is not awarded without violating the green on green rule.

Affected By Denial Mode

The N-PBS Scheduler had to deny some or all of your bids in order to build you a complete block.

Affected by SLG

The N-PBS Scheduler could not build you a block using any of your preferences and reached the end of Denial mode. Due to this, your block is built using Secondary Line Generation (SLG).

Affected By Coverage

A pairing or pairings are forced onto your block to meet airline targets for the total number of pairings remaining in open time.
