It wasn’t clear from the report whether the taxi was used before or after a duty, which is an important detail. Use of a taxi for transport to a duty period can be considered a flight safety issue since the journey might impact how the crew member was subsequently able to perform when on flying duties. For example, having an anxious crew member reporting for duty after being driven by a dangerous taxi driver could adversely affect their performance/decision making in flight. However, a taxi journey after a flight is arguably a matter of duty of care/ employer safety. Notwithstanding, a company always has a duty of care to their employees even when some of its functions and roles are subcontracted, such as taxi/transport provision. When functions are subcontracted, the airline still needs to ensure sufficient oversight to be able to assess performance of the contract but also, as this reporter emphasizes, that safety aspects are also being met.
