Flight  cancellation is a process in which there are several steps to follow as described below:1-

1. Flight to be canceled, operating frequency ,dates of effectiveness. It may be just a date specific flight or a date range. In that case the item must be divided first, considering the dates range and / or frequencies that will be processed (see DIVISION OF FLIGHTS).

1. Flight cancellation process begins according to the following steps:

Step 1:

KA*4580  Flight items to be modified are displayed

Step 2:

KS.1 Item parameter to modify is selected

Response:

INM(Inventory) requested item is displayed

Step 3:

KSGCANCEL Selected item is canceled 

Response:

1 FLIGHTS (42) PAX IN (17) PNRS AFFECTED
DONE 

System responds the number of affected flights,passengers and PNRs. By the time the flight is canceled the process is not finished yet. This can be verified by doing  the KS entry which will display the item with the  *** CANCEL ** warning. If after executing KSGCANCEL command should be necessary to ignore or restore the selected item the entry is: KSGCANCEL / UNDO

This command ignores the flight cancellation and restores it.

Response:

FLIGHTS (42) PAX IN (17) PNRS RESTORED
DONE 

Then the response is the number of flights,passengers and restored PNRs.

Once the command KSGCANCEL is done ,it is not possible to do the KA*ALL entry in the same window. If you attempt to do so the response will be :

NOT PERMITTED. SCHEDULE PROCESS. 

KA* entry can be done by changing areas.

Before processing definitively you must perform passenger re-accommodation.

Description as follows; 

Step 4:

Passenger Re-accommodation

After the flight cancellation process, points of origin, destination or modification , the command must be made to re-accommodate passengers.
The re-accommodation can be automatic or manual.

Automated re-accommodation

Command to execute the automatic re-accommodation is:

KSREAC

This action relocates passengers on other flights (in case of cancellation), following a pre-established parameter (tables previously configured according to the administrator convenience  or in  the same flight(in the case of modification).
To see the listings for automatic system re-accommodation  you can use the "resetting list" commands (explained below).
Once the reset command has been made, the system processes all the PNRs and automatically adapts them according to the configured tables. If you do not find any option, leave the PNR without re-accommodation (you can see the option of "Manual reset" below).

The system has two possible responses:

KSREAC
REAC COMPLETED 

First response is when the re-accommodation has been completed and PNRs relocated.

KSREAC
REACCOMODATION PROCESS ....INCOMPLETED
PAX NOT REAC : 14

Second response is when re-accommodation is not complete for any reason. (inexistent flight,route,class,or other item to relocate.  Number of passengers not relocated.

Duplicities in re-accommodation

If  the re-arrangement process results in PNRs duplication the system detects those PNRs and leaves them without re-accommodation to avoid duplication.

The message that  will be displayed  appear in the re-accommodation lists is:

						NOT REAC BY DUPE **** 

Re-accommodations List

Maximum Analytic filter by booking code

KSRL0 

It is the most analytical list that allows to view the passengers that are going to be re-accommodated by date, code, route, class ,booking status and also the flight in which the re-accommodation will take place or if there is no re-accommodation available also.

Description:

• Re-accommodated item on another flight

REAC LEVEL 0 FLT- 4360 FILTER: NONE

• Re-accommodation level  0 flight number 4360 Filter : none 

ITEM  DATE      CODE   BRDOFF C ST#

23JUL 4420 AEPMDQ 12:05 13:15 Y Flight detail from where re-accommodation took place

• Not re-accommodation item

Those items that are NOT REAC are those that could not be automatically re-accommodated.

00004 23JUL2006 EFZDVW AEPVDM Y HK2 - NOT REAC

• Re-accommodated item on the same flight

Those items in which « (left commas)  is observed at the end  will indicate that the flight will be re-accommodated in itself.

00003 01OCT2005 FHUVJV AEPBRC Y HK1   «  

00004 01OCT2005 HVZEJF AEPBRC B HK1   «  

00005 01OCT2005 PHKAQT AEPBRC N HK1   « 

• Re-accommodated item  on the same flight replacing the modified route

  • In these cases, when one airport is replaced by another and the goal is that passengers are re-accommodated within the same flight. (See CHANGE OF ORIGIN OR DESTINATION)

Example:

 00011 22JUL2006 YKLXIK AEPRGL Y HK3   « REAC FORCED * RGL=CRD00012 22JUL2006 OFPNAJ AEPRGL B HK2   « REAC FORCED * RGL=CRD

In this case RGL has been replaced by CRD and passengers have been re-accommodated within the same flight , but replacing  RGL by CRD

Maximum Analytical filter by class 

KSRL3

This filter displays in a more discriminated way the number of passengers that are going to be re-accommodated differentiated by class, date or route.

Unlike the previous one, this list does not discriminate by code, but groups the number of passengers by date of flight, route and booking class.

Those items that are NOT REAC are those that have found automatic re-accommodation.

Like the previous one, it can be done before or after  KSREAC command and it can also be used for a manual re-accommodation

Maximum Analytical filter by route

KSRL5

This filter displays in a more discriminated way the number of passengers that are going to be re-accommodated, differentiated by class, by date and by route.

Unlike the previous one, this list does not discriminate by code, but groups the number of passengers by date of flight, route and booking class.

Those items that are NOT REAC are those that have found automatic re-accommodation.

Like the previous one, it can be done before or after the KSREAC command and it can also be used for a manual re-accommodation.

Those items that are NOT REAC are those that have ben processed by the automated re-accommodation

KSRL5 REAC LEVEL 5 FLT-4360  FILTER:

00004 23JUL2006 MDQBHI     3 - NOT REAC 

Re-accommodation list filter

There are filters that can be applied in these list to further specify the options.
These indicators are added to the command list. These filters are:

N          Not Re-accommodated Passengers

R          Re-accommodated passengers

X          Passengers without re-accommodation but manually forced to do so.

M         Passengers with manual re-accommodation

A         Automated re-accommodation passengers 

Examples:
KSRL5N
KSRL3X
KSRL0M

Manual re-accommodation

When no chance for automatic re-accommodation was found within the tables nor it is not the desired one, it is possible to change to manual re-accommodation. It must be executed from a re-accommodation list.

The steps are the following:

• List is retrieved.

Example:

KSRL0 
REAC LEVEL 0 FLT-4360  FILTER:  NONE 

 ITEM DATE      CODE   BRDOFF C ST#       
00001 23JUL2006 CMKJOH AEPMDQ Y HK1    - 23JUL 4420 AEPMDQ 12:05 13:15   Y 
00002 23JUL2006 PJLZCA AEPMDQ B HK1    - 23JUL 4420 AEPMDQ 12:05 13:15   B 
00003 23JUL2006 RZLWXG AEPBHI Y HK1    - 23JUL 4350 AEPBHI 12:00 13:00   Y 
00004 23JUL2006 EFZDVW AEPVDM Y HK2    - NOT REAC 
00005 23JUL2006 TKMMSF AEPVDM Y HK1    - NOT REAC 
00006 23JUL2006 NONPTH MDQBHI Y HK2    - NOT REAC 
00007 23JUL2006 QTFWNS MDQBHI Y HK1    - NOT REAC 

• From this list the items that must be re-accommodated are taken and alternate flights must be chosen in order to have the items relocated.

• Example:

KSRL0.4-5/4360AEPVDM25JUL

Description:

• When retrieving this list,the modified items will be displayed in the following way:

00004 23JUL2006 EFZDVW AEPVDM Y HK2 * 25JUL 4360 AEPVDM 06:00 09:00 Y

• Another option is when the flight  where re-accommodation will take place does not have the same classes, you  will  have to force the system to replace nonexistent classes with others that are loaded on the new flight.

Example 1:

KSRL0.4-5/4360AEPVDM25JUL-Y

• -Y  Replaces  actual class by Y  

• If only -Y is set, all classes of the selected items will be replaced by class Y

KSRL0.4-5/4360AEPVDM25JUL-YA-BR Replaces Classes A by Y, R by B

• If -YA is set, the first class (in this case Y) will be the replacement of the second class (in this case A). You can load the number of necessary classes always separated by a hyphen.

• System response in all cases will be OK.

• When retrieving  the list again, the re-accommodated segments will be seen with the flight data where they were accommodated preceded by an asterisk (star) and the classes that were replaced (A / Y) and (R / B)
  This procedure can be repeated as many times as necessary until all the items are re-accommodated.

• In case the intent is to leave some items without re-accommodation, the system must be forced to execute such procedure in the following way:

KSRL0.9/NOTREAC

System response must be OK, and, when retrieving the list, the selected item should read:

											**NOT REAC OK **

Example:

*00009 25APR2005 EVOEKX AEPBRC R HK1 * NOT REAC OK ** 

Manual re-accommodation can also be done from lists such as KSRL3 and KSRL5.

Example:

KSRL5 

REAC LEVEL 5 FLT-4104  FILTER: NONE 

 ITEM DATE     BRDOFF     #       
00001 23MAR20018 AEPTUC     7 - 23MAR 4102 AEPTUC 10:00 12:00 00002 
23MAR2004 AEPTUC    18 - NOT REAC 
00003 23MAR2018 AEPSLA    10 - 23MAR 4102 AEPSLA 10:00 13:00 
00004 23MAR2018 AEPSLA    18 - NOT REAC 
00005 23MAR2018 AEPJUJ    26 - NOT REAC 
00006 23MAR2018 TUCJUJ    30 - NOT REAC 

After displaying this list a re-accommodation will be requested

KSRL5.1-2/4104AEPTUC22MAR

When requesting the list again, you can see that items 1 and 2 were grouped into one and the order of the rest was changed.

KSRL5 
REAC LEVEL 5 FLT-4104  FILTER: NONE 

 ITEM DATE      BRDOFF     #

00005 23MAR2018 TUCJUJ    30 - NOT REAC  

Clear Manual re-accommodation

A command to clear manual re-accommodation is available which allows to return to the original automated re-accommodation:

KSREAC/CLEAR 

The objective is to restore the original re-accommodation:

System response:

REAC COMPLETED 

Step 5: Validation

Once the corresponding re-accommodations have been made, you must proceed to validate and record the cancellation of the flight by executing the following command:

KSAVE

Response:

DONE

Passenger re-accommodation (No flight cancellation)

The command to re-accommodate passengers without cancelling the flight is as follows:

KSGREAC

Steps to re-accommodate passengers (without cancelling the flight where they are):

1. KA*<FLIGHT>
2. KS.<ITEM>
3. KSGREAC
4. KSRL0 or KSRL3 or KSRL5
5. KSREAC o KSRL<NBR>.1-50/<FLIGHT><ORIG><DEST><DATE>
6. KSAVE
