Delta Air Lines Inc. said some ticket prices were incorrectly displayed today on its website and other booking channels, resulting in customers purchasing flights at lower than usual fares.

The situation has been resolved and Delta will honor any fares purchased at the incorrect price, the airline said in an e-mailed statement. Delta, based in Atlanta, said the low fares were displayed “for a portion of the morning” and it’s investigating what happened.

Customers had reported the low fares, such as round-trip flights across the country for $50, on Twitter. Amanda Maher of Boston, who was contacted by Bloomberg News, said she got confirmation of a purchase on that was later canceled.

In September, United Airlines allowed passengers who bought tickets that were accidentally offered for free because of faulty reservations data to use them for travel. Delta didn’t say how many tickets were sold today at the incorrect price.
