This route earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 1,494 LBB to DAL flights, with a median arrival 10 minutes early.
Best time to fly LBB to DAL: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 96.1% of the time and Wednesday flights 90.8%, against 84.9% for the route overall.
Set against the rest of the country, this route's record is 8 points better than the US average of 77.3%. That gap is worth roughly 76 fewer late arrivals for every thousand flights.

These figures cover 1,494 flights between September 2025 and August 2026. The median arrival is 10 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.

Best ways to make this trip
The most reliable ways to fly Lubbock to Dallas
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 2 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. LBB → DFWLubbock to Dallas-Fort Worth | Envoy Air | 85.7% | 86.7% | 1.21% | 5am–8am, Tue | — |
| 2. LBB → DALLubbock to Dallas | Southwest Airlines | 83.9% | 84.9% | 1.14% | 5am–8am, Wed | — |
| 3. LBB → DFWLubbock to Dallas-Fort Worth | SkyWest Airlines | 77.0% | 79.2% | 2.75% | 8am–11am, Wed | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 27 points, against half a point between the best and worst carrier.
- 5am–8am364 flights96.1%
- 8am–11am199 flights92.8%
- 11am–2pm224 flights86.9%
- 2pm–5pm340 flights80.0%
- 5pm–8pm328 flights73.5%
- 8pm–5am39 flights69.2%
Scale runs 60% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 96.1% of the time, against 69.2% for the overnight window. That is 27 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 364 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 24 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
June is the worst month at 68.5% on time, 24 points below February, the best at 92.6%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. December was the busiest month here, with 140 flights.
Across the week, Wednesday is the strongest day at 90.8% on time and Sunday the weakest at 79.8%, a spread of 11 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 54% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 24%National Airspace System
- 15%Carrier
- 7%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 14,720 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 96.1% on time here.
Cancellations sit at 1.14% against a national 1.89%, which is ordinary. Diversions add another 0.20%.
Connections and stage length
What a delay here actually costs
5.3% of arrivals land an hour or more late, close to the national 8.3%, so 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.
At 293 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.1% on time across 1,494 flights, 8 points below 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 8 points of difference.
The sample behind these figures is 1,494 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. February runs 92.6% on time and June 68.5%, a swing of 24 points. If the dates move at all, move them out of June before you think about anything else. 1,474 completed flights over 12 months sit behind that.
Common questions
LBB to DAL questions
How often is LBB to DAL delayed?
About one flight in seven arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 15.1% of the 1,494 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is LBB to DAL compared with the rest of the country?
84.9% of flights arrive on time here against a national 77.3%, a difference of 8 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on LBB to DAL?
The 5am–8am departure window is the strongest at 96.1% on time. The 8pm–5am window is the weakest at 69.2%, 27 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are June delays on LBB to DAL?
June is the weakest month at 68.5% on time, compared with 92.6% in February. Across the year that is 24 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
