Try something like this where we alias the joined tables:
SELECT departure_date, j1.code AS departure_code, j2.code AS arrival_code
FROM jsjourneys
LEFT OUTER JOIN jsports AS j1 ON jsjourneys.departure_port = j1.id
LEFT OUTER JOIN jsports AS j2 ON jsjourneys.arrival_port = j2.id;
As a side note - all the IATA codes are unique for each airport - wouldn't
it be better to use these as the Primary Key and Foreign Keys? Then you
wouldn't have to even join the tables unless you wanted the port names (not
just the code)
