Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5660, 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 5660 earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 348 flights, with a median arrival 13 minutes early.
Set against the rest of the country, YX 5660's record is 9 points better than the US average of 77.6%. That gap is worth roughly 93 fewer late arrivals for every thousand flights.

These figures cover 348 flights between July 2025 and June 2026. The median arrival is 13 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 5660 flies
YX 5660 flies IND to LGA without a single fixed slot. Its most common scheduled departure was 08:00, used on 181 of 348 flights, with 08:05 (47 flights) and 08:10 (35 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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 5660 runs 3 points better at 86.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
YX 5660 quarter by quarter
YX 5660 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.5% on time and its weakest Oct–Dec 2025 at 82.1%, a swing of 11 points on roughly 87 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 flights93.5%
- Oct–Dec 202580 flights82.1%
- Jan–Mar 202686 flights84.4%
- Apr–Jun 202690 flights86.4%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, YX 5660 did best on Saturday at 91.8% on time and worst on Tuesday at 79.2%. Each day rests on about 50 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 5660 runs late
One category carries most of the weight here. Carrier accounts for 70% of the 3,071 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 70%Carrier
- 20%National Airspace System
- 9%Extreme weather
- 1%Late-arriving aircraft
- 0%Security
The largest share of delay minutes, 70%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,143 of the 3,071 delay minutes reported here. The split is drawn from 3,071 delay minutes reported on YX 5660.
Cancellations run at 3.16%, against 1.81% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.2% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 660 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on one other city pair in the data, including RDU to BOS (11), but none flew often enough under YX 5660 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to LGA only.
One caution: this is a thin sample. 348 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 5660
For a booking, the cancellation rate is the figure to plan around on YX 5660: 3.16% of its 348 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
