What You Can Learn From British Airways's IT Meltdown That Left Passengers StrandedInvest in systems you need and keep your customers informed.

British Airways had a rough weekend.

Due to a power surge early Saturday morning and a backup that failed to work, the airline'scomputer systemsbroke down. The crash prompted British Airways to cancel all departing flights from Heathrow and Gatwick airports, effectively stranding 75,000 people. And once the passengers arrived at their destinations, there was no guarantee that their luggage would be waiting for them.

It was a chaotic and ultimately expensive mishap for British Airways. The marketvalueof IAG, the airline's parent company, dropped by about $643,550,000. Not only that, butThe Guardianreports that customers inconvenienced by the IT issues had to pay up to $2,059 in additional travel costs, leaving the company with a hefty compensation $192 million compensation bill.

If you're sleeping on the floor of an airport terminal, of course you aren't going to have a ton of understanding for the organization that put you in that position. But it wasn't just disgruntled passengers -- the response from rival airline, Ireland's Ryanair was particularly merciless.

Cruz is saying all the right things, and it would seem that his team is working tirelessly to make sure that each customer is taken care of. But what the experience of British Airways teaches us is that we need to think carefully about where resources can best be utilized. Think about the systems and structures that you can't do without and always make sure that they are up to date. If you can have the most current technology, an investment now could save you a major headache later.

Better that the glitch never happened at all -- but if your company is faced with a snafu of this magnitude, the best move is to be honest, admit what went wrong and keep your customers informed.
