Boeing and the United States Federal Aviation Administration have grounded the worldwide fleet of 737 MAX aircraft as concern grows about its airworthiness.

At the core of every airline is its flight schedule – how it manages thousands of flights carrying millions of passengers to cities around the world.

Power has been resorted at Hartsfield-Jackson International Airport in Atlanta after an electrical fault caused a partial shut-down on Sunday evening. Tens of thousands of passengers were delayed following the incident at the busiest airport in the world.

Southwest Airlines has announced a new tentative agreement with Transport Workers Union Local 555. The union represents more than 12,000 Southwest ground operations, provisioning, and cargo agents. The Union’s Executive Board reviewed an Agreement in Principle that negotiators reached December 23rd and decided to conduct a ratification vote that could end more than four years of negotiations.

The first-ever scheduled international flights flown by Southwest Airlines took off earlier heading to the Caribbean, also marking the successful full implementation of Amadeus’ Altéa Suite, the next generation passenger services system for airlines. “We have realised our vision of flying internationally, and this success is a testament to the hard work, dedication, and expertise of the combined Southwest and Amadeus teams,” said Randy Sloan, Southwest Airlines senior vice president and chief information officer.

Southwest Airlines today operates its first revenue flight utilising a Boeing 737-800 equipped with Aviation Partner’s Boeing Split Scimitar Winglets.  The newly designed winglet differs than those currently installed on the carrier’s fleet of Boeing 737s, with aerodynamic scimitar tips and a large ventral strake on the bottom of the blended winglet structure.
