Across the year

UA 1997 quarter by 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 269 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 88 departures that left 15 minutes late or more, only 7 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 IAD.

Delay causes

Why UA 1997 runs late

Late-arriving aircraft accounts for 53% of the 8,035 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    53%
  • National Airspace System
    30%
  • Carrier
    13%
  • Extreme weather
    4%

53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,035 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 8,035 delay minutes reported on UA 1997.

Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

19.0% 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 758 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 1997 is not only a MCO to IAD flight. It also flew IAD to EWR (265 flights, 77.6% 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. 272 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 1997

For a booking, UA 1997 is a flight to put a long connection behind. 19.0% 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.
