Our guide explains how the SLC-SFO route appears on a tracker map.

Can the Boeing 737-900ER comfortably fly DL686?

Not at all. At roughly 18% of its range, this is an easy trip for a Boeing 737-900ER. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 737-900ER.

What to know about DL686

  • Time change: you land 1 hour behind the time you left.
  • High airport at the start: SLC sits 4,227 ft up. Thin air means a longer takeoff run.

What we know about DL686

What flying SLC to SFO takes

It is a short-haul sector, a single-aisle hop where turnaround time matters more than range. Delta Air Lines needs a narrowbody such as an A320 or 737 family aircraft: comfortably inside single-aisle range with fuel to spare for a diversion. The two ends are not symmetric. Salt Lake City is roughly 4,214 ft higher than the other airport, so the same aircraft is planned differently in each direction. In daylight the sun sits on the left (south-facing) side of the cabin for most of the crossing.

How we verified this

The origin and destination on this page are the ones we verified for callsign DAL686 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 34 days between 2026-09-20 and 2026-10-23. Timings are observations, not an official operational status: always confirm with the airline before travelling.

This page was published from our own tracking record rather than a third-party schedule feed, so it grows as we see the flight again. The seven-day log below is the raw version of the same evidence.

DL686 activity in the past 7 days

Our database contains 8 observations of DL686 across 8 UTC dates in this window, most recently 2026-10-23. Those records contain 7 distinct transponder addresses. The most frequently resolved route was SLC-SFO (8 records).

The median recorded visibility was 54 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does DL686 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 737-900ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown962 km
AircraftBoeing 737-900ER
Fuel burn rate3.83 kg per km
Fuel burned3,683 kg
CO2, whole flight11.6 tonnes
Seats, typical layout178
Passengers carried148 at an 83% load factor
CO2 per passenger79 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 79 kg cabin average and a flat bed well above it.

Economy157 seats, 130 flown
65 kg CO2 per seat
Business21 seats, 17 flown
188 kg CO2 per seat

Taken whole, DL686 emits what 194 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 463 km, or 2,247 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 926 km sector, the only published sector for this type, applied to this route's 962 km unadjusted. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put DL686 against another flight.
