Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3530, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

YX 3530 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 359 flights, with a median arrival 4 minutes early.

These figures cover 359 flights between July 2025 and June 2026. The median arrival is 4 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When YX 3530 flies

YX 3530 flies IND to IAD without a single fixed slot. Its most common scheduled departure was 14:35, used on 89 of 359 flights, with 14:40 (69 flights) and 14:34 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 14:35 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 3530 runs 8 points better at 80.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 3530 quarter by quarter

YX 3530 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.3% on time and its weakest Oct–Dec 2025 at 70.7%, a swing of 19 points on roughly 90 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.

Jul–Sep 202592 flights75.6%
Oct–Dec 202592 flights70.7%
Jan–Mar 202690 flights88.5%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, YX 3530 did best on Thursday at 86.5% on time and worst on Sunday at 70.0%. Each day rests on about 51 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 3530 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,220 reported delay minutes.

National Airspace System
36%
Late-arriving aircraft
35%
Carrier
27%
Extreme weather
2%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,220 reported delay minutes here, that single category outweighs weather by 16 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,220 delay minutes reported on YX 3530.

Cancellations sit at 1.39% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

Connections and routes

What a delay on this flight costs

6.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The same number turns up on two other city pairs in the data, including EWR to JAX (5) and JAX to EWR (1), but none flew often enough under YX 3530 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to IAD only.

One caution: this is a thin sample. 359 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 YX 3530

For a booking, read YX 3530 as 80.7% on time with 1.39% cancelled over 359 flights. Those are rates from the past twelve months, not a forecast for any particular day.
