Delay causes
Why SkyWest runs late on this route
Carrier accounts for 71% of the 4,380 delay minutes carriers reported here, and the remaining four split what is left.
- 71%Carrier
- 14%National Airspace System
- 12%Extreme weather
- 3%Security
Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 4,380 reported delay minutes.
The largest share of delay minutes, 71%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,113 of the 4,380 delay minutes reported here.
Cancellations are rare at 0.68%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
18.6% 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.
At 302 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 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 73.6% on time across 146 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 146 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 SkyWest on ATL to MOB
Put together: treat all of this as provisional. 146 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 67.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 145 completed flights over 12 months sit behind that.
