The spokesman, Al Becker, said the airline and its agency, Temerlin McClain, Irving, Texas, are developing concepts for the spots "related to the notion of what has occurred in our world. This has been a cataclysmic development for our whole nation and the industry. It can't be ignored. It's changed everything profoundly."
The airline has been running full-page print ads with a back-to-business theme in about 20 newspapers since last week, Mr. Becker said.
