On 11 May 2019, Bristow Group entered Chapter 11 bankruptcy protection, affecting North America operations, but leaving overseas operations unchanged.
After an aggressive expansion earlier in the decade, demand was cut back as crude oil prices dropped and Bristow Group’s total debt stood at $1.44 billion by 30 September 2018.
Bristow completed the UK's Eastern Airways sale on 10 May, and still wants to sell its interest in Australia's Airnorth, hoping for $230 million combined.
In 1996, Bristow Helicopters was purchased by Offshore Logistics, an American offshore helicopter operator which operated as Air Logistics in the U.S. Gulf of Mexico and Alaska, and was structured as a reverse takeover. The group now operates and maintains a global fleet of over 400 aircraft. In 2006 Offshore Logistics re-branded itself as 'The Bristow Group'.
The Bristow Group expanded their portfolio in April 2007 with the purchase of Helicopter Adventures, a Florida-based flight school, Helicopter Adventures was subsequently renamed Bristow Academy. The deal also provided the Bristow Group with the world's largest civilian fleet of Schweizer aircraft.
Bristow (formerly Air Logistics)
In January 2010, Bristow announced the retirement of the Air Logistics name and Gulf of Mexico operations would operate under the name Bristow. Bristow provides helicopter services, maintenance and other support services to the oil and gas industry. It operates more than 170 single and twin-turbine helicopters in the United States. These receive support, materials and operational assistance from its regional headquarters and primary maintenance facility located at the Acadiana Regional Airport in New Iberia, Louisiana.
Bristow has controlling interests in Eastern Airways which is a regional airline based in the U.K. operating fixed wing regional jet and turboprop aircraft and Airnorth, also a regional airline, based in Australia operating fixed wing regional jet and turboprop aircraft. Both Eastern Airways and Airnorth operate scheduled passenger services, shuttle flights for oil and gas industry personnel, and charter services.
In addition to its wholly owned international operations, Bristow Group maintains service agreements and equity interests in helicopter operators in Brazil, Canada, Colombia, Egypt, Kazakhstan, Turkmenistan, Mexico, Norway and Russia (Sakhalin) and the United Kingdom. This allows Bristow to extend its range of services into new and developing oil and gas markets and helps provide a lower cost structure in some operating areas. Partners include:
Although not a joint venture, in 2015 Bristow and AgustaWestland agreed to develop offshore and search and rescue capabilities for the AW609tiltrotor. This could simplify a typical trip from Clapham Common to an oil rig by using just one aircraft. Bristow intends to order more than 10 tiltrotors.
All the Defence Helicopter Flying School Helicopters and Synthetic Training Equipment are owned by FB Heliservices, a consortium of Bristow Helicopters and FR Aviation, who provide 40% of the instructional staff, all the ground school and simulator staff, carry out all maintenance and provide support services.
On 26 March 2013 Bristow was awarded a 10-year contract to operate the search and rescue operations in the United Kingdom, at the time being provided by CHC Helicopter (on behalf of Her Majesty's Coastguard), the Royal Air Force and the Royal Navy. Bristow is currently operating AgustaWestland AW139, AgustaWestland AW189 and Sikorsky S-92 helicopters in support of this contract. The AW139 aircraft are being replaced by the AW189 which was originally specified in the contract however procurement delays lead to the AW139 being introduced instead of the AW189 initially, resulting in AAR AIrlift Group claiming the first civilian registered SAR AW189, based in the Falkland Islands, in support of the UK Government 
Bristow operates a large fleet of over 450 helicopters and aircraft, which includes unconsolidated affiliates and joint venture partners. Bristow intends to reduce fleet variety from 24 helicopter types to six. For subsidiaries Eastern Airways and Airnorth fixed wing jet and turboprop aircraft, see Eastern Airways and Airnorth.

On 4 July 1983, Bristow Helicopters AS332L Super Puma (G-TIGD) crashed on landing at Aberdeen. During the approach to Aberdeen from the North Hutton platform, a loud bang was heard, followed by severe vibration. A PAN call was made to ATC by the crew. Shortly before landing control was lost and the helicopter struck the runway heavily on its side. 10 of 16 passengers received serious injuries. A tail boom panel had become detached in flight and damaged all five tail rotor blades. The resulting imbalance to the tail rotor assembly led to the separation of this unit and subsequent loss of control.

The 22-year-old helicopter was flying at an altitude of about 320 feet (98 m) when workers on the Global Santa Fe Monarch heard "a loud bang". No witnesses were actually watching the aircraft at the time, but some saw it dive steeply into the sea. A witness also reported seeing the helicopter's rotor head with rotor blades attached falling into the sea after the body of the helicopter had impacted.
