A hub turn combines two pairings into one, following specific rules. These pairings are considered “Hub Turnable”.
- Only one hub turn can be added per bid line.
- The N-PBS system does not verify hub turn eligibility during bidding. If a pairing does not qualify as a hub turn, a message appears in the Reasons Report after bidding ends.
- Hub turn and follow can not be used on the same bid line.
Hub Turnable Pairings Criteria
Pairings must meet all criteria to be considered hub turnable:
- The hub turn must originate from HNL bases (Joint Base Pearl Harbor–Hickam, Hawaii) and be an international pairing.
- The total combined duty, from the last Check-In of the first pairing to the end of the final Check-Out of the second pairing, can not exceed 14 hours.
- There must be at least one hour between the arrival time of the last flight of the first pairing and the departure time of the first flight of the second pairing.
Reminder:
The N-PBS Scheduler uses the arrival time of the last flight of the first pairing and the departure time of the first flight of the second pairing.
Note: Pairing’s Check-In and Check-Out times are not used for this purpose.
Example of Hub Turnable Pairings
- The last flight of pairing H6713 departs at 9:15, with a Check-In at 8:00.
- The first flight of pairing H6716 arrives at 21:40 and checks out at 21:55.
- The combined duty period is 13 hours and 55 minutes (21:55 - 8:00), which is less than the 14-hour maximum.
Bid Example
Award Pairings If Departing On Monday, Tuesday Hub Turn
- Pairings are awarded if both pairings are Hub Turnable and depart on Monday or Tuesday.
Note: Hub Turn is an all-or-nothing bid. If the second pairing is not Hub Turnable, the first pairing is not awarded, even if the first pairing is legal.
