United began testing a new boarding process this week at all of its gates in Los Angeles airport (LAX).
The process utilizes just two boarding lanes, rather than the five that United has been using for the last five years.
Under the trial procedure, Group 1 will board through Lane 1 and Group 2 will board through Lane 2.
After that groups three, four and five will board through Lane 2 when called, while groups one and two may continue to board through Lane 1.
"We ask that you wait until your group has been called before lining up," an explanation on United's website says.
The trial is a follow-up to one United conducted at Cleveland Hopkins airport last year. The carrier is hoping the altered boarding process will result in fewer passengers lining up before their group is called. That in-turn, would result in easier access to and from the gate during the pre-boarding process and for passengers getting off other flights.
United also said it hopes to increase efficiency by boarding customers sitting in window seats first, followed by those sitting in center seats and aisle seats. That process, however, will only apply after passengers with priority boarding are called onto their flight.
Along with those changes, the LAX trial includes new boarding signage, and United is texting customers on select flights to let them know when boarding has begun.
"Our customers have told us they want a better experience when boarding, so we're working to improve the process by testing a new boarding method at various airports across our network," the carrier said.
