AERO CALL SIGNS and AIRLINE CODES
often heard in low level airspace around the Maritimes, particularly near Halifax
Last update March 13, 2010

2-letter and 3-letter codes are those used on schedules, arrival/departure lists, and on air movements webpages.   Subsidiary or feeder airlines often utilize the codes of the airlines they serve.  for example, Jazz and Georgian are usually identified on airport arrival/departure screens as AC as they are integrated and marketed as part of Air Canada's system.   The subsidiary airline's own codes may be less commonly seen, and are indicated below preceding a slash.

Some of the listed airlines are occasional visitors.   This list does not include airlines whose aircraft were merely diverted to Halifax, nor does it include aircraft passing overhead but not landing at Halifax.
