DL 2098 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs close to two hours. That rests on 364 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 2098's record is 10 points better than the US average of 77.3%. That gap is worth roughly 102 fewer late arrivals for every thousand flights.

These figures cover 364 flights between September 2025 and August 2026. The median arrival is 9 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 DL 2098 flies

DL 2098 flies AUS to BOS without a single fixed slot. Its most common scheduled departure was 07:20, used on 257 of 364 flights, with 07:25 (85 flights) next.

A 07:20 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2098 runs level with that at 87.5%. 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

DL 2098 quarter by quarter

DL 2098 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.6% on time and its weakest Jan–Mar 2026 at 77.1%, a swing of 19 points on roughly 73 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.

By weekday, DL 2098 did best on Thursday at 94.2% on time and worst on Saturday at 80.8%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 2098 runs when it is late

DL 2098 often beats the schedule: 107 of 353 completed flights, 30%, arrived 15 minutes or more early. The 44 late arrivals split 20 under half an hour, 8 between 30 and 60 minutes, and 16 an hour or more.

Share of 353 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 28 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 19 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 BOS.

The worst days

Worst days for DL 2098

The latest arrival of the period was on 26 September 2025, 11 hours 1 minute behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as a late-arriving aircraft.

Delay causes

Why DL 2098 runs late

Carrier accounts for 43% of the 5,018 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
43%
Late-arriving aircraft
40%
National Airspace System
17%

40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,018 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 5,018 delay minutes reported on DL 2098.

Cancellations run at 3.02%, against 1.89% nationally. That is roughly 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 4.5% land an hour or more behind schedule, against 8.3% 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.

At 1,698 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 364 flights under DL 2098 in the data flew AUS to BOS. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 364 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 DL 2098

For a booking, the cancellation rate is the figure to plan around on DL 2098: 3.02% of its 364 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
