The term LAX DATA refers to the Los Angeles International Airport (LAX) data. ETAS and ETDS are two acronyms related to this data. ETAS stands for Estimated Time of Arrival and Departure, which is the estimated time that a plane will arrive or depart from the airport. ETDS stands for Estimated Time of Departure and Scheduled Time of Arrival, which is the estimated time that a plane will depart from the airport and the scheduled time that it will arrive. Both ETAS and ETDS are important pieces of information for travelers and airport personnel.
