WASHINGTON (Reuters) - The U.S. Federal Aviation Administration said Wednesday it had completed a safety review of Southwest Airlines ( LUV ) it opened in July after a series of incidents including some that raised serious concerns.

The FAA said it had completed the review and that it "did not identify any significant safety issues."

Southwest ( LUV ) said it appreciated the opportunity to engage with the FAA "as part of our mutual dedication to safety."

The FAA opened the review after a Southwest ( LUV ) flight in July flew at a very low altitude over Tampa Bay, Florida, one of a series of flights that had raised questions.
