Carrier by carrier
Spirit against every carrier on EWR to IND
Spirit flew 253 of the 2,204 flights on EWR to IND, about 11% of it. Its 68.8% on time is 13 points worse than the route as a whole, which runs 81.7%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from United at 100.0% to Spirit at 68.8%. One 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.

Delay causes
Why Spirit runs late on this route
National Airspace System accounts for 46% of the 5,010 delay minutes carriers reported here, and the remaining four split what is left.
- 46%National Airspace System
- 28%Late-arriving aircraft
- 24%Carrier
- 2%Extreme weather
- 0%Security
46% 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 2,294 minutes out of 5,010, against a national NAS share of 21%. The split is drawn from 5,010 reported delay minutes.
Cancellations run at 5.14%, against 1.89% nationally. That is about one flight in twenty 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 stage length
What a delay here costs
13.8% 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 645 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.
The return leg is a different operation and performs like one: it runs 89.5% on time across 254 flights, 21 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 21 points of difference.
One caution: this is a thin sample. 253 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 Spirit on EWR to IND
Put together: the delay figures matter less here than the 5.14% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 240 completed flights over 12 months sit behind that.
