LONDON: London’s Heathrow Airport resumed full operations on Saturday, a day after a fire knocked out its power supply and shut Europe’s busiest airport, causing global travel chaos.
The travel industry was scrambling to reroute passengers and fix battered airline schedules after the huge fire at an electrical substation serving the airport.
Some flights had resumed on Friday evening, but the shuttering of the world’s fifth-busiest airport for most of the day left tens of thousands searching for scarce hotel rooms and replacement seats while airlines tried to return jets and crew to bases.
Teams were working across the airport to support passengers affected by the outage, a Heathrow spokesperson said in an emailed statement.
“We have hundreds of additional colleagues on hand in our terminals and we have added flights to today’s schedule to facilitate an extra 10,000 passengers traveling through the airport,” the spokesperson said.
The travel industry, facing the prospect of a financial hit costing tens of millions of pounds and a likely fight over who should pay, questioned how such crucial infrastructure could fail without backup.
“It is a clear planning failure by the airport,” said Willie Walsh, head of global airlines body IATA, who, as former head of British Airways, has for years been a fierce critic of the crowded hub.
The airport had been due to handle 1,351 flights on Friday, flying up to 291,000 passengers, but planes were diverted to other airports in Britain and across Europe, while many long-haul flights returned to their point of departure.
Heathrow Chief Executive Thomas Woldbye said he expected the airport to be back “in full operation” on Saturday.
Asked who would pay for the disruption, he said there were “procedures in place,” adding “we don’t have liabilities in place for incidents like this.”
Restrictions on overnight flights were temporarily lifted by Britain’s Department of Transport to ease congestion, but British Airways chief executive Sean Doyle said the closure was set to have a “huge impact on all of our customers flying with us over the coming days.”
Virgin Atlantic said it expected to operate “a near full schedule” with limited cancelations on Saturday but that the situation remained dynamic and all flights would be kept under continuous review.
Airlines including JetBlue, American Airlines, Air Canada, Air India, Delta Air Lines, Qantas, United Airlines, British Airways and Virgin were diverted or returned to their origin airports in the wake of the closure, according to data from flight analytics firm Cirium.
Shares in many airlines fell on Friday.
Aviation experts said the last time European airports experienced disruption on such a large scale was the 2010 Icelandic volcanic ash cloud that grounded some 100,000 flights.
They warned that some passengers forced to land in Europe may have to stay in transit lounges if they lack the paperwork to leave the airport.
Prices at hotels around Heathrow jumped, with booking sites offering rooms for 500 pounds ($645), roughly five times the normal price levels.
Police said after an initial assessment, they were not treating the incident at the power substation as suspicious, although enquiries remained ongoing. London Fire Brigade said its investigations would focus on the electrical distribution equipment.
Heathrow and London’s other major airports have been hit by other outages in recent years, most recently by an automated gate failure and an air traffic system meltdown, both in 2023.

BERLIN: Germany on Friday approved three billion euros ($3.25 billion) in new military aid for Ukraine, just days before planned US-brokered talks with Moscow and Kyiv on a limited truce.
The money is earmarked for defense equipment for the country fighting Russian forces, including munitions, drones, armored vehicles and air-defense systems.
The parliament’s budget committee gave the green light for the funds, which had been on hold for months amid discord in the coalition government of outgoing Chancellor Olaf Scholz.
But the final adoption on Friday of a major new spending package that also eased Germany’s strict debt rules for defense outlays gave the government new room for maneuver.
President Volodymyr Zelensky thanked Germany for the new aid in a post on X, saying it would provide “exactly what Ukraine needs most — what saves Ukrainian lives.
“This means contracts with the German defense industry will now be signed for future — a significant step toward building long-term security guarantees,” Zelensky said.
“It is also a recognition that Ukraine’s army will become even stronger after the war ends, and Germany is committed to contributing to that.”
Greens MP Britta Hasselmann, whose party has strongly pushed for Ukraine aid, expressed relief the new billions were being released, “albeit late.”
She called it “a strong signal to Ukraine, a signal that is absolutely necessary for peace and security in Europe.”

The new money comes on top of four billion euros in Ukraine military aid already planned in Germany’s budget for 2025.
A further 8.3 billion euros were earmarked for Kyiv for 2026 to 2029.
Government spokesman Steffen Hebestreit has said the latest package would include units of the German-made Iris-T air-defense systems that had yet to be built and would be delivered over the next two years.
Germany has been Ukraine’s second-largest supplier of military aid after the United States, contributing some 28 billion euros so far since Russia launched its full-scale invasion over three years ago.
But the situation has changed dramatically since US President Donald Trump reached out to Russia’s Vladimir Putin to end the war and suspended military aid to Ukraine. He also cast doubt on America’s commitment to NATO.

Russia and Ukraine on Friday traded accusations of massive overnight attacks, three days before both sides will hold talks with US officials in Saudi Arabia on how to halt the war.
Both countries have said they agree with a 30-day pause in strikes on energy targets, though they have continued their aerial attacks unabated.
Each has repeatedly accused the other of breaking the truce, which has not been formally agreed.
Germany’s chancellor-in-waiting Friedrich Merz, whose party won February elections, has pushed through a spending package worth hundreds of billions to bolster Germany’s armed forces and infrastructure and to keep backing Ukraine.
Merz’s conservatives are in coalition talks with the SPD of Scholz, who has also vowed that Germany would keep supporting Kyiv.
Ukraine “can rely on us and we will never leave it on its own,” Scholz said at a European Council summit late Thursday.
“It will also need a strong army in times of peace, and it must not be put in danger by any peace agreement.”
