Tens of thousands of flights have already been canceled this summer as the industry struggles to cope with demand for air travel amid staff shortages. The Times reported that BA had suspended tickets for domestic and European services until Monday to comply with Heathrow’s passenger cap, with the airport announcing last month that no more than 100,000 daily departing passengers would be allowed until on September 11. The airline earlier responded to Heathrow’s passenger cap by announcing it would cancel 10,300 flights until October, with one million passengers affected. Many passengers flying to and from the UK’s busiest airport have suffered severe disruption in recent months, with long security queues and baggage system breakdowns. Emirates last month rejected Heathrow’s order to cancel flights to comply with the cap. The airline accused the airport of showing “blatant disregard for consumers” by trying to force it to “deny seats to tens of thousands of travellers” through the cap. A Heathrow spokesman said at the time that it would be “disappointing” if “any airline wants to put profits ahead of a safe and reliable passenger journey”. Virgin Atlantic also criticized the airport’s actions and claimed responsibility for failures contributing to the chaos. On July 21 the airlines were accused of “harmful practices” in the treatment of passengers affected by the disruption. The Competition and Markets Authority and the Civil Aviation Authority issued a joint letter to air carriers, expressing concern that “consumers could suffer significant harm unless airlines meet their obligations”. The letter said: “We are concerned that some airlines may not be doing everything they can to avoid one or more harmful practices.” These include selling more tickets for flights “than they can reasonably expect to provide”, not always “fulfilling obligations” to offer flights on alternative airlines to passengers affected by cancellations and failing to provide consumers with “sufficiently clear and advance information about their rights”.
