Dozens of British residents in Spain were refused travel because airlines refused to take in as proof of residency documents used until the United Kingdom's departure from the European Union at midnight on Dec. 31, 2020. Airlines refused documents that before Brexit had been valid proof of the Britons' status as residents in Spain, Italy and Germany, although Spanish authorities claimed that the issue had been resolved by mid-Sunday. Around 300,000 British citizens are registered as permanent residents in Spain, although before Brexit, many more had been living full or part-time in the country without officially registering. Spain has been rolling out a new system to register permanent foreign residents called TIE but it’s suffering a backlog due to the high number of requests. “This should not be happening,” said the U.K. embassy in Spain said in a Facebook post.

The airline says the pilot program will offer voluntary testing starting Nov. 25 in partnership with American Airlines for passengers flying to Heathrow from New York, Los Angeles and Dallas. Passengers will be tested 72 hours before departure, on arrival at Heathrow and again three days after arrival. Passengers who test positive will be able to rebook their flights free of charge, BA said. Heathrow Airport said last month that it had lost its place as Europe’s busiest air hub as France and Germany relaxed quarantine rules and implemented testing regimes. BA said more airlines may join the testing program in the coming weeks.

LONDON – The parent company of British Airways has cut its fourth-quarter passenger forecast to just 30% of last year’s level as government restrictions imposed to control a new wave of coronavirus infections reduces demand for flights. International Airlines Group made the announcement Thursday as it posted a third-quarter operating loss of 1.3 billion euros ($1.7 billion), compared with a profit of 1.4 billion euros in the same period last year. The company said it reduced the fourth-quarter passenger forecast because of additional restrictions, including “an increase in local lockdowns and extension of quarantine requirements to travelers from an increasing number of countries.’’The company said that measures meant to mitigate the disruption, such as pre-departure testing and air corridor arrangements, “have not been adopted by governments as quickly as anticipated.''

LONDON – Britain’s information commissioner has fined British Airways 20 million pounds ($25 million) for failing to protect personal data for some 400,000 customers, the largest fine the agency has ever issued. The ICO said in a statement Friday that the airline was processing personal data without adequate security measures. It also noted that it did not detect a 2018 cyber attack for two months. Information Commissioner Elizabeth Denham said says BA’s “failure to act was unacceptable and affected hundreds of thousands of people, which may have caused some anxiety and distress as a result.’’Under the European Union's General Data Protection Rules imposed in 2018, organizations face fines of up to 20 million euros ($23 million) or 4% of annual global turnover — whichever is greater — for the most serious violations.

LONDON – British Airways has replaced CEO Alex Cruz after 4 1/2 years on the job as part of a broad shake-up as the COVID-19 pandemic pummels airlines around the world.

Donal Moriarty will become interim chief executive of Aer Lingus, with a permanent appointment to come later.

Aircraft G-CIVY, one of the last two British Airways Boeing 747-400 aircraft takes off for its last flight departure from London's Heathrow Airport, Thursday, Oct. 8, 2020. The retirement of the fleet was brought forward as a result of the impact the Covid-19 pandemic had on the airline and the aviation sector. It remained the largest commercial aircraft in the world until the Airbus A380 first took to the skies in 2007. More than 1,500 jumbos were produced by Boeing, and it has historically been a commercial success for the manufacturer and the airlines. “It’s a beautiful design, a classic like Concorde, and I often think the upper deck made the 747 look more birdlike.”

LONDON British Airways parent company said Thursday it will cut flights due to coronavirus travel restrictions and quarantine requirements and confirmed it is raising 2.7 billion euros ($3.2 billion) through the sale of new shares. Qatar Airways, which owns 25% of IAG, has undertaken to take its share of the cash call. Over the past few weeks, British tourists in particular have faced travel chaos after the government took countries off its safe list. Other airlines have also had to cut back on flights, including EasyJet, which earlier this week bemoaned the unpredictable restrictions. It also said it has reached an agreement in principle with the Unite union over changes to the pay and conditions of British Airways cabin crew, with a ballot expected shortly.

(AP Photo/Daniel Cole)LONDON London's Heathrow Airport, the U.K.'s busiest, unveiled a new coronavirus testing facility Wednesday that it says could halve the length of time people have to stay at home after arriving from countries on the British governments quarantine list. Over the past few weeks, British tourists have faced travel chaos after the government took countries off its safe list at very short notice. The new facility has been set up by aviation services company Collinson and logistics firm Swissport at Heathrows Terminal 2. The statistics agency will increase the number of people it tests under the survey from 28,000 every two weeks to 150,000 by October.

British holidaymakers in France were mulling whether to return home early Friday to avoid having to self-isolate for 14 days following the U.K. government's decision to reimpose quarantine restrictions on France amid a recent pick-up in coronavirus infections. The Netherlands, Malta, Monaco and the Caribbean islands of Aruba and Turks & Caicos have also been added to the quarantine list for the same reason. Travel companies are urging anyone considering a swift return home to check whether they will be able to do so. While the number of new infections in Britain is also rising, they are not thought to be increasing at the same pace as in the countries added to the quarantine list. The quarantine decision is a big blow to France's tourism industry, which is heavily reliant on travelers from Britain.

LONDON The parent company of British Airways reeled to a loss of 3.8 billion euros ($4.5 billion) in the first six months of the year as travel restrictions from the COVID-19 pandemic ate into the bottom line. The company announced it plans to raise 2.75 billion euros through a proposed capital increase. Chief Executive Willie Walsh predicted that passenger levels wouldnt return to pre-virus levels until 2023, and that it is restructuring its cost base to reduce each airlines size.The group has already announced 12,000 cuts at British Airways. Walsh says the scale of the challenge eclipses the downturn faced by the industry after the Sept.11, 2001 attacks. Anyone who believes that this is just a temporary downturn and therefore can be fixed with temporary measures, Im afraid seriously misjudges what the industry is going through,'' he said.

The biggest single loan of 1 billion pounds ($1.25 billion) went to German chemical company BASF.

Stuart C. Wilson/Getty Images(CNN) - British Airways pilots have called off a strike planned for Sept. 27 after their union said that action taken earlier this month had "demonstrated the anger and resolve of pilots." British Airways was forced to cancel virtually all flights for two days in early September after the union called a strike amid a heated dispute over pay. British Airways posted an operating profit of nearly 2 billion ($2.5 billion) for 2018, an 11.6% increase over the previous year. The union said it retains the right to announce further strike dates if British Airways refuses "meaningful new negotiations." British Airways, which is owned by International Consolidated Airlines Group, did not immediately respond to a request for comment.

Stuart C. Wilson/Getty Images(CNN) - This week's British Airways strike has caused chaos for an estimated 280,000 passengers who were due to fly with the airline. All eight daily easyJet flights from Nice to London were sold out on Monday and Tuesday, the British Airways strike days. British Airways is selling return fares to Nice on other dates in September for 58 -- making this week's flights nearly 22 times as expensive. Ironically, the flight is sold as a British Airways flight, but operated by Air Belgium, so it is exempt from the strike action. A two-night trip to Tokyo, departing Monday, cost 2,704 ($3,341), going out on Japan Airlines in premium economy (economy was sold out) and returning Wednesday in economy on British Airways.

LONDON - On August 25, 1919 the first regular international passenger air service took place between London, England and Paris, France. Clearly international flights have changed a lot in the past 100 years, so let's take a look back at where it all began. Still, 100 years ago, aviation was often the sole realm of brave adventurers and experienced aviators, so the daily London to Paris passenger flight, although it also transported mail and parcels, represented a new era in commercial flying. After all, the first non-stop flight from London to Paris took place only seven years earlier, and the first powered flight took place just 16 years earlier. "Although there were scheduled flights and aviation is developing and growing, it's not massive [...] It's still for the well-off people," he said.

Stuart C. Wilson/Getty Images(CNN) - British Airways pilots will strike in September for three days over a pay dispute, the first pilot walkout in about four decades. Their union, the British Airline Pilots Association, on Friday announced the three dates September 9, 10 and 27 adding that it had proposed several packages to British Airways that had been rejected. It will be the first time BA pilots have gone on strike since the 1970s. The union estimated that the three days of strikes would cost the airline about 120 million, or roughly $147 million. British Airways called its pay offer of an 11.5% increase over three years "fair" and above the United Kingdom's current rate of inflation.

VALENCIA, Spain - A British Airways flight from London to Spain was evacuated after smoke filled the cabin moments before the flight was due to land. British Airways confirmed a "technical issue" on flight BA422, which was traveling from London Heathrow to Valencia on Monday afternoon, and said passengers were evacuated from the aircraft. We don't know why oxygen masks didn't deploy." Passenger oxygen masks were not deployed because they, "unlike pilot and cabin crew oxygen systems, are not designed to be used in smoke events as they mix the oxygen supply with the ambient air." British Airways said there were two pilots and six cabin crew on board.

Peter Macdiarmid/Getty ImagesLONDON - British Airways pilots have voted by a big majority to strike, escalating a pay dispute with the airline that could throw the summer travel season into disarray. Members of the British Airline Pilots Association working for the airline voted 93% in favor of a strike action, the union announced Monday. The conflict stems from a fight over pay that the pilot's association said it has been negotiating since late last year. The pilots association also represents Ryanair pilots who are based in the United Kingdom. It announced last week that it will be issuing a ballot to its Ryanair members to decide on a possible strike action Wednesday.
