Airlines’ old IT systems, budget cuts in spotlight

British Airways’ failure a call for industry-wide improvements.

LONDON — The catastrophic IT failure at British Airways that ruined travel plans for 75,000 people has raised questions about some older airlines’ focus on costs to the detriment of investment in new computer systems.

As British Airways resumed full service Tuesday, shares in its parent company, International Airlines Group, dropped 3 percent as investors appeared to worry that the company’s quality of service may have been undermined by recent efforts to save money.

Disaster struck on Saturday, when the company’s computer systems went down and there was no functioning back-up.

The airline cancelled all flights and only managed to resume full service on Tuesday.

“Although cost cutting has been good for the share price in the last year, it will come back to bite IAG if it stops them from doing what they are supposed to do: Fly passengers to their destinations,” said Kathleen Brooks, the research director at City Index.

IAG has been battling tough competition, even as it has faced pressure on its earnings from a weaker pound following Britain’s decision to leave the European Union.

The company issued a profit warning following the Brexit vote nearly a year ago.

Cost pressures aggravated an already complicated situation. Renewing IT systems is complex, time-consuming and expensive — a factor that prompts many companies to put it off as long as possible, said Loizos Heracleous, a professor of strategy at Warwick Business School.

The problem with IT systems is recurring across the industry, particularly among established airlines.

In August 2016, Delta Air lines had to cancel hundreds of flights when a power outage likewise knocked out its computer systems worldwide.

Airlines face challenges with their IT systems also due to linkages across their systems.

There’s further demand on the system when companies consolidate — as has been the case among airlines — since “IT issues get heightened and any vulnerabilities are exposed.”

Such troubles give an advantage to newer airlines such as Ryanair, a cost-cutting BA rival that focuses on short haul budget flights.

“The ability to set up an airline from scratch by-passes a lot of the legacy issues, because you can go for state-of-the-art systems,” Heracleous said.

“Newer airlines can also invest in IT systems that are more easily upgradeable and scaleable. An airline such as Ryanair, that is also financially successful, has more leeway to divert needed resources towards upgrading its IT systems,” he added.

Ryanair said it had seen “strong bookings” over the weekend. Its Twitter account rubbed salt into the wound with tweets that poked fun and added the hashtag “Should Have Flown Ryan air .”

The company’s chief marketing officer, Kenny Jacobs, said, “We don’t take social media seriously but we do take IT very seriously and that is why we’ve never had an outage.”
