Republic on BGR to ORD sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land about an hour behind schedule. That rests on 170 flights, with a median arrival 10 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on BGR to ORD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Republic against every carrier on BGR to ORD
Republic flew 170 of the 712 flights on BGR to ORD, about 24% of it. Its 75.6% on time is about level with the route as a whole at 74.6%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from Envoy at 90.0% to United at 30.0%. Four of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

The 5pm–8pm window is where this operation falls apart: 51.0% on time, against 95.6% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 50 flights scheduled in it.

Share of 168 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 26 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 17 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.
The worst days
Worst days for Republic on BGR to ORD
The latest arrival of the period was on 31 August 2026, 3 hours 13 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 31 August 2026 | 3 hours 13 minutes | National Airspace System |
| 12 August 2026 | 3 hours 7 minutes | Late-arriving aircraft |
| 13 September 2025 | 2 hours 54 minutes | Extreme weather |

Delay causes
Why Republic runs late on this route
National Airspace System accounts for 48% of the 2,756 delay minutes carriers reported here, and the remaining four split what is left.
- 48%National Airspace System
- 36%Late-arriving aircraft
- 11%Carrier
- 5%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,756 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 2,756 reported delay minutes.
48% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,317 minutes out of 2,756, against a national NAS share of 21%.
Cancellations sit at 1.18% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
9.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 978 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
One caution: this is a thin sample. 170 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Republic on BGR to ORD
Put together: treat all of this as provisional. 170 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 75.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 168 completed flights over 12 months sit behind that.
