Across the year
UA 2608 quarter by quarter
UA 2608 did not run the same all year. Its best quarter was Apr–Jun 2026 at 70.0% on time and its weakest Jan–Mar 2026 at 53.1%, a swing of 17 points on roughly 71 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 274 completed flights by arrival against schedule.
13 of 100 late departures made up the time and arrived on time, 13% of them. In the other direction, 25 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 EWR.
The worst days
Worst days for UA 2608
The latest arrival of the period was on 27 February 2026, 8 hours 25 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across February, November, March and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 February 2026 | 8 hours 25 minutes | Late-arriving aircraft |

Delay causes
Why UA 2608 runs late
National Airspace System accounts for 51% of the 9,088 delay minutes carriers reported here, and the remaining four split what is left.
- 51%National Airspace System
- 30%Late-arriving aircraft
- 18%Carrier
- 1%Extreme weather
51% 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 4,632 minutes out of 9,088, against a national NAS share of 21%. The split is drawn from 9,088 delay minutes reported on UA 2608.
Cancellations sit at 1.77% against a national 1.89%, which is ordinary. Diversions add another 1.06%.
Connections and routes
What a delay on this flight costs
17.9% 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 1,400 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.
UA 2608 is not only a IAH to EWR flight. It also flew LAS to IAH (262 flights, 95.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 282 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 UA 2608
For a booking, UA 2608 is a flight to put a long connection behind. 17.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
