Harbour Air is a regional operator based in Richmond, Canada. The airline operates one of the largest seaplane fleets in the world which are utilised on a small scheduled route network. The airline commenced operations in 1982 performing charter flights for the forestry industry of British Columbia. In 1993, the airline acquired Trans-Provincial airline, which facilitated increased frequency of scheduled flight services and passenger capacity.

The airline operates a variety of aircraft types, many of which can be modified with float or ski landing gear allowing for take off and landings at water aerodromes and frozen lakes. Throughout the 2000s, the airline continued to expand and in 2012, purchased fellow Canadian operator; Whistler Air. Then in 2015, Salt Spring Air was also purchased and amalgamated into Harbour Air's mainline operation. As a result of these acquisitions, Whistler Air, Tantalus Air and Salt Spring Air all operate under the Harbour Air branding and flight codes. It is important to note that some aircraft may feature the individual branding of each of these airlines.

In mid 2017, the airline operated a fleet of de Havilland aircraft, with an average age over 59 years. Whilst the airline's fleet is considered to be very old, this is not unusual for small seaplane operators.

The Civil Aviation Administration of China (CAAC) has imposed a small fine (USD$ 4,270) on Emirates following a pair of safety incidents in April and May 2017. On the 17th April, the CAAC reportedly stated that an Emirates flight crew had misinterpreted Air Traffic Control (ATC) instructions and flown the aircraft at the incorrect altitude which subsequently resulted in a loss of separation with another aircraft. The second incident occurred on the 18th May, an Emirates aircraft lost radio communication with ATC due to the flight crew changing frequencies prematurely.

On the 5th June 2017, a number of Arab States including Bahrain, Saudi Arabia, Egypt, Libya and the UAE, announced they would sever all diplomatic ties with Qatar effective immediately. As a result, flight services to and from these nations have been affected. A number of airlines have announced the suspension of flights to Qatar including Emirates, Etihad Airways and Air Arabia. In addition to the take-off and landing ban imposed on the airline, Qatar Airways is now required to divert around a number of states airspaces. Following this decision, Saudi Arabia's General Authority of Civil Aviation (GACA) announced they had revoked Qatar Airways’ operating licence and ordered the closure of the airline’s offices in Saudi Arabia.
