Voluntary Standby Rules

Some Passengers might be eligible for the voluntary standby on another flight which reaches the same destination as their original segment (first available segment in the reservation). To enable this feature, it is needed to set the following configuration to 'true':

s4ci.checkin.eligibility.voluntaryStandbyCalculationEnabled

When one of the Passengers is eligible to voluntary standby, Digital Connect Check-In returns the eligibility on the reservation level:

{
  "reason": [
    {
      "category": "ALLOWED_VOLUNTARY_STANDBY",
      "message": "Passenger are eligible for voluntary standby"
    }
  ],
  "type": "STAND_BY",
  "notEligible": false
}

The calculation is done by using standby rules according to the priorities in a descending order.

The single rule may contain the following criteria:

Priority - required
Booking class
Brand
Frequent flyer tier level
Origin (city, country, airport)
Destination (city, country, airport)
Window start (default: check-in window start)
Window end (default: check-in window end)
Decision (ALLOWED/DENIED) - required

Rules Examples

Example 1
```
[ {
  "priority" : 3,
  "bookingClass" : "J",
  "decision" : "ALLOWED",
  "windowStart" : "PT48H",
  "windowEnd" : "PT2H",
  "origin" : "Airport/AUH",
  "destination" : "Country/DE"
}, {
  "priority" : 5,
  "fqtvTierLevel" : "PLT",
  "decision" : "ALLOWED",
  "origin" : "City/NYC"
}]
```
It means that the Passenger is eligible for the voluntary standby when:
- Has frequent flyer tier level = PLT and flies from New York City
  The rule applies during the check-in window hours.
or
- Has booking class = J and flies from AUH to Germany
  The rule applies between 48 hours before the flight to 2 hours before the flight.
Example 2
```
[{
  "priority" : 7,
  "bookingClass" : "Y",
  "decision" : "DENIED"
}, {
  "priority" : 4,
  "brand" : "SF",
  "decision" : "ALLOWED",
  "windowStart" : "PT72H",
  "windowEnd" : "PT12H"
}]
```
It means that the Passenger is eligible for the voluntary standby when:
- Has other booking class then Y
  The rule applies during the check-in window hours.
or
- Has brand = SF
  The rule applies between 72 hours before the flight to 12 hours before the flight.
