Starting 4, Southwest Airlines is making a small yet noticeable adjustment to its inflight experience. Cabin preparations for landing will start at 18,000 feet instead of the prior 10,000 feet. That’ll correlate with a 10-minute sooner request to raise tray tables,

In-flight service, such as the sale of food and beverages, will soon end ten minutes earlier on Southwest flights.

Additional changes are coming to Southwest Airlines this week as the airline says "nothing is more important" than the safety of customers and employees.

Starting Dec. 4, Southwest flight attendant crews will wrap up in-flight service at 18,000 feet to begin preparing the cabin for landing sooner, a spokesperson for the Dallas-based carrier confirmed to ABC News.
