Choose your departure airport and the service you need. A reservations number is different from an airport desk’s direct line. Counter assignments and check-in deadlines can change; check your own flight on the departure screens and with the airline.
Go to Terminal 7 for United check-in, as shown on LAX’s airline location map dated July 1, 2026. The terminal number is not a counter number. Check your booking and United’s instructions for the counter assignment and check-in deadline.

The LAX airline directory lists this United contact. Use it for airline assistance; it is not a verified direct line to the airport check-in desk. For missing checked baggage, ask the operating airline’s arrivals baggage team for the appropriate report.
For a United international departure from San Francisco, check in on the International Terminal’s Departures Level (Level 3). Business and Premium passengers use Aisle 1; Economy passengers use Aisle 2. Aisles are check-in rows, not boarding gate numbers. This is separate from United’s domestic Terminal 2 and Terminal 3 listings. Ask United for the counter opening time and your flight’s check-in deadline; security checkpoint hours are not check-in hours.
SFO lists this number as United’s Baggage Service. It is a baggage support channel, not a verified direct phone for a check-in counter or a particular arrivals desk. If your checked bag is missing or damaged, contact the operating airline’s arrivals baggage team and keep the report number.
