MINNEAPOLIS (AP) - Delta Air Lines says it may have charged some frequent fliers higher fares than other customers for almost three weeks because of a computer glitch.
Delta says it is unsure how many travelers paid higher fares because of the problem. Delta says the problem occurred after it upgraded the flight search engine on its website. The airline reverted to its old search engine after discovering the problem.
Two businessmen booking the same flight from Minneapolis to St. Louis noticed the problem a few weeks ago. They tried booking a number of flights while sitting side-by-side and saw the fare differences several times.
