British Airways has been fined $1.1m (£878,000) by the US government over claims it neglected to pay refunds for canceled flights during the pandemic.

The US Division of Transportation said the airline had not given "timely refunds to passengers" for abandoned or rescheduled flights to and from the country.

It said it had gotten in excess of 1,200 complaints about the airline.

BA rejected the cases, saying it had "acted legally consistently".

As indicated by the transport department, from March to November 2020, BA's site instructed consumers to contact the carrier by telephone to talk about refund options, including for flights the carrier had canceled or significantly changed.

However, consumers were unable to get through to customer service agents when calling the carrier for several months during this period because BA failed to maintain adequate functionality of its customer service phone lines, it said.

"There was also no way to submit a refund request through the carrier's website during this period," the department said.

It added that from March to November 2020, misleading information on BA's website had led consumers to inadvertently request travel vouchers instead of refunds.

It said that along with the 1,200 complaints received by the department, BA had received thousands more complaints and refund requests directly from consumers.

The department said the failures had "caused significant challenges and delays in thousands of consumers receiving required refunds".

It added that the fine established a "strong deterrent to future similar unlawful practices".

BA will be credited $550,000 towards the penalty because it paid more than $40m in refunds to customers with non-refundable tickets in 2020 and 2021.

The airline said: "We're very sorry that at the height of the unprecedented pandemic - when we were unfortunately forced to cancel thousands of flights and close some call centers due to government restrictions - our customers experienced slightly longer wait times to reach customer service teams.

"During this period, we acted lawfully at all times and offered customers the flexibility of rebooking travel on different dates or claiming a refund if their flights were cancelled.

"To date, we have issued more than five million refunds since the start of the pandemic."

Not good enough.
