Hi,
You can use JOIN statement. Check the below code.
DATA: BEGIN OF WA,
        CARRID TYPE SPFLI-CARRID,
        CONNID TYPE SPFLI-CONNID,
        FLDATE TYPE SFLIGHT-FLDATE,
        BOOKID TYPE SBOOK-BOOKID,
      END OF WA,
      ITAB LIKE SORTED TABLE OF WA
                WITH UNIQUE KEY CARRID CONNID FLDATE BOOKID.
SELECT PCARRID PCONNID FFLDATE BBOOKID
INTO   CORRESPONDING FIELDS OF TABLE ITAB
FROM   ( ( SPFLI AS P
           INNER JOIN SFLIGHT AS F ON PCARRID = FCARRID AND
                                      PCONNID = FCONNID      )
           INNER JOIN SBOOK   AS B ON BCARRID = FCARRID AND
                                      BCONNID = FCONNID AND
                                      BFLDATE = FFLDATE      )
WHERE P~CITYFROM = 'FRANKFURT' AND
      P~CITYTO   = 'NEW YORK'  AND
      FSEATSMAX > FSEATSOCC.
LOOP AT ITAB INTO WA.
  AT NEW FLDATE.
    WRITE: / WA-CARRID, WA-CONNID, WA-FLDATE.
  ENDAT.
  WRITE / WA-BOOKID.
ENDLOOP.
