American Airlines resumes flights after brief grounding due to technical issue

American Airlines has resumed operations after a brief grounding due to a technical issue. The Federal Aviation Administration ordered the grounding early Tuesday at the airline's request, affecting flights across the U.S. The issue arose just before a busy travel period, with millions expected to fly for the holidays. American Airlines communicated with travelers on social media, assuring them that the problem was being addressed. The grounding was lifted after regulators cleared the airline to resume flights. The Transportation Security Administration anticipates screening 40 million passengers during the holiday season.
