After technical issues that caused outsized delays in December, Southwest communicated little, trying to downplay more service disruptions yesterday. The first tweet, shown here, responded to a customer complaint. The second tweet accurately describes the issue as a “pause,” a term a New York Times article repeats, based on the time period. But the impact on passengers was significant: 1,820 flights (43% of the airline’s daily flights) were delayed. A silly gif with moving clip art appeared in the second message for no reason.

On the Southwest website, a short “Operational Update” tries to shift blame to a supplier: “a vendor-supplied firewall went down and connection to some operational data was unexpectedly lost.” Later, a “Travel Advisory” apologized to customers and gave options for no-fee rebooking and standing by—and a list of phone numbers for assistance.

Critics say Southwest’s “outdated” technology might cause more problems until a systemwide upgrade is possible. One communication strategy is to manage customer expectations in the meantime. Telling people to expect delays might ease some pain; of course, that could lead to fewer bookings, but that may likely happen anyway. Passengers will need to be reminded about other benefits of traveling with Southwest.
