GateCast grades your connection from A to F on how likely you are to make it, using a year of real flight records. At Newark, pairs of United flights scheduled 45–59 minutes apart were missed on 15% of the days they ran, Aug 2025 – Jul 2026; pairs 90–120 minutes apart, on 6%.
How often United connections here were missed
Every pair of United flights at Newark (regional flights sold as United 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 United 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.
