On the 23rd July 2017, Singapore Airlines, the owner of both Tigerair Singapore (Originally Tiger Airways TR/TGW) and Scoot, announced that the two airlines will be consolidated into a single carrier under the Scoot name and branding. As a result, Tigerair aircraft will be repainted in Scoot livery and colours, a process that is not expected to be completed by 2018. However the TR flight code will replace Scoot’s TZ code. The merger was completed at the end of July, with both airlines set to utilise a single reservation, ticketing and scheduling system. Tigerair Taiwan and Tigerair Australia will continue to operate under their respective brands.

Yemenia (Yemen Airways) is the flag carrier of Yemen, and operates domestic and international services from its home bases at Sana’a International Airport and Aden International Airport. The airline commenced operations in 1962. The current name, Yemenia, was adopted in 1978, following the joint establishment of the Government of Yemen and the Government of Saudi Arabia. Both governments still jointly own the airline.

In 2011, Yemenia commenced the process of renewing its fleet when it took delivery of its first of ten Airbus A320 aircraft. Additionally, the airline had also placed orders for an additional ten Airbus A350 aircraft. However, by late 2014, the airline had only taken delivery of a total of two aircraft out of the original ten that had been ordered. Furthermore, the airline has also reduced its fleet to just three operational aircraft from mid-2012 to mid 2017. While this had allowed the airline to reduce its average overall fleet age by approximately eight years, it also indicated that the airline was likely experiencing significant constraints as a result of the deteriorating security environment within Yemen.

In mid 2016 it was observed that Yemenia no longer featured on the IOSA Registry, however, remained listed as an IATA member. In late 2016, the airline's IATA membership was also removed. As a result, the airline's adherence to internationally recognised safety standards could not be wholly verified.

On 7th July, an Air Canada Airbus A320-200 was on final approach to land at San Francisco International Airport in night conditions. As the aircraft descended, the flight crew questioned their landing clearance with Air Traffic Control (ATC) as they could see a number of unidentifiable lights on the assigned runway. ATC confirmed the clearance however; another pilot reported that the Airbus flight crew that they had mistakenly aligned with the taxiway adjacent to the runway. This prompted the flight crew to initiate a go around procedure before re-positioning and performing a safe landing. The Canadian Transport Safety Board has launched an investigation and reported that the Airbus overflew four aircraft awaiting departure on the taxiway with the vertical separation being reduced to less than 100 feet above the first aircraft.
