Numbers from Aug 2025 – Jul 2026 flight records · generated 1 October 2026
GateCast grades your connection from A to F on how likely you are to make it, using a year of real flight records. At Los Angeles, pairs of Delta flights scheduled 45–59 minutes apart were missed on 12% of the days they ran, Aug 2025 – Jul 2026; pairs 90–120 minutes apart, on 4%.
How often Delta connections here were missed
Every pair of Delta flights at Los Angeles (regional flights sold as Delta included), grouped by the scheduled time between them, and checked against what actually happened on each day both flights ran, Aug 2025 – Jul 2026.
"Missed" means the first flight was cancelled, or arrived too late to leave about 31 minutes to get off, reach the next gate and board before the doors close. That time is our estimate for Delta connections here: flight records don't say which passengers made their connection. Days when the second flight was cancelled aren't counted. Pairs scheduled less than 35 minutes apart are left out, because we can't tell which of those the airline would sell as a connection.

What decides a connection at Los Angeles
- At Los Angeles, half of travellers arriving from abroad without Global Entry waited 19 minutes or less at passport control, and 1 in 10 waited more than 48 minutes (24 September 2025 – 23 September 2026).US Customs and Border Protection, Airport Wait Times (awt.cbp.gov), 24 September 2025 – 23 September 2026, checked 25 September 2026
- Almost all international arrivals at Los Angeles collect their checked bags, clear US customs, check them in again and go back through security before the next flight. On some routes, eligible connecting passengers skip the bag recheck but still go back through security: for example, Korean Air from Seoul (since June 2026, according to the airline's announcement). Check with your airline. Flights that clear US preclearance before they leave are also an exception. It runs at 16 airports (ten in Canada, including Toronto, Montreal and Vancouver, plus Dublin, Shannon, Nassau, Bermuda, Aruba and Abu Dhabi), though not on every flight from them; a flight that clears it arrives at Los Angeles as a domestic flight.
