MySQL with AND statement – Database administrators stack Exchange

I have problems with this question:

Find cities with direct flights to Honolulu and Newark.

Enter the image description here

The answer should be Dallas, as it is the only location that has both destinations as well as Honolulu and Newark. I try that AND Statement, but it will not work.

SELECT FLIGHTS.source_city
OF FLIGHTS
WO (FLIGHTS.destination_city = # Honolulu #) and (FLIGHTS.destination_city = # Newark #)

I use MySQL.
