Question: List the flight date of flights with air carrier described as Profit Airlines Inc.: XBH which have an actual elapsed time below 100.
Evidence: flight date refers to FL_DATE; Profit Airlines Inc.: XBH refers to Description = 'Profit Airlines Inc.: XBH'; actual elapsed time below 100 refers to ACTUAL_ELAPSED_TIME < 100;

SQL:
SELECT T2.FL_DATE FROM `Air Carriers` AS T1 INNER JOIN Airlines AS T2 ON T1.Code = T2.OP_CARRIER_AIRLINE_ID WHERE T2.ACTUAL_ELAPSED_TIME < 100 AND T1.Description = 'Profit Airlines Inc.: XBH'
