Passenger alert: Delta is on the move at LAX

West coast-bound fliers take note: Delta Air Lines is moving its operations at Los Angeles International in a project that will cause hassles for travelers and require 20 other airlines to relocate.

The good news is that the bulk of the project, which starts Friday, should be completed by the middle of next week.

Atlanta-based Delta is moving from Terminals 5 and 6 to Terminals 2 and 3 at LAX, allowing it to expand and be closer to international partners.

Delta advises that people traveling through LAX during the relocation and the weeks following should check in online, print boarding passes and check terminal and gate information before heading to the airport.

They also should allow extra time for walking through the airport – Delta is advising passengers at LAX to arrive at least three hours before domestic flights and four before international flights. The airline also plans for its Fly Delta app to offer turn-by-turn directions.

Connecting between some terminals will require shuttle rides that can take up to 45 minutes and walks of up to 35 minutes, according to Delta’s website on the move, which can be found by googling “Investing in LAX.”

LAX also has a website, laxishappening.com, with information on the move including maps and tips.

Once the move is complete, Delta will have a bus between Terminals 2 and 3 and the international terminal so customers don’t have to leave the secure part of the airport and go through security again to connect.

The move and related projects are part of $1.9 billion in improvements Delta plans at LAX over the next seven years.

Delta operates about 175 flights per day from Los Angeles International, more than doubling its presence since 2009.
