Spokesman Chris Mainz said the airline called Pamela Root on Friday to apologize. He says Root also will receive a refund and a $300 travel voucher.
The crew bounced Root and her son Adam off the San Jose-bound flight because passengers could not hear preflight safety announcements.
Root says she was confident Adam's screams of "Go! Plane! Go!" and "I want Daddy!" would subside after the plane took off Monday in Amarillo, Texas.
The 38-year-old mom said she hoped to be compensated for the portable crib and diapers she had to buy for the extra night away from home.
