LOS ANGELES (AP) — A labor march could delay Thanksgiving eve travelers at Los Angeles International Airport on one of the busiest travel days of the year.

Members of the Service Employees International Union are expected to march between 11 a.m. and 4 p.m. Wednesday outside the Century Boulevard entrance to the airport.

The union is in a dispute with an airport services company that terminated SEIU contracts last year.

Airport officials say travelers should add 90 minutes to their planned airport arrival time on top of the usual two hours before a domestic flight and three hours before an international flight.

All airport entrances will remain open.
