How often Delta connections here were missed
Every pair of Delta flights at New York LaGuardia (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.
