Airlines investigated for failing to offer refunds
Airlines are being investigated by the competition watchdog over concerns they breached consumer rights by failing to offer cash refunds for flights passengers could not take amid the pandemic.
The Competition and Markets Authority (CMA) said its probe will look at situations where airlines continued to operate flights despite people being unable lawfully to travel for non-essential purposes, such as during England's second lockdown last month.
It said that in some cases where flights were not cancelled, customers were told to rebook or offered a voucher rather than a refund.
Andrea Coscelli, chief executive of the CMA, said: "We will be carefully analysing all the evidence to see whether any airlines breached consumers' legal rights by refusing people cash refunds for flights they could not lawfully take.
"We recognise the continued pressure that businesses are currently facing but they have a responsibility to treat consumers fairly and abide by their legal obligations."
The CMA said it will write to "a number of airlines" to request information about their approaches to refunds for passengers prevented from flying by lockdown restrictions.
It will analyse the evidence before deciding whether to launch enforcement action against individual carriers.
The watchdog will work closely with aviation regulator the Civil Aviation Authority during its investigation.
Taxi drivers will protest outside the Scottish Parliament on Wednesday against what they call a lack of support for the industry during the pandemic.
