    a perfectly-perfect connection i discovered by accident a while back:

    SFO ORD 070° (E) 056° (NE) 1,846 mi
    ORD JFK 092° (E) 096° (E) 740 mi
    2,586 mi

    SFO JFK 070° (E) 056° (NE) 2,586 mi

    how much does the connection save the traveler? for STL-YYZ on random dates, $209, $140, & 173 v $219. Only July 28, the DTW connection is more expensive than the non-stop. I suppose with a large enough data set you could some general numbers.

      Depends wildly on the city pair and other factors. In some cases the “perfect” connection would be a mixed carrier itinerary that would blow up pricing.

      This was more about realizing how many airports are in good connection locations for typical great circle routes. DUB shows up in the list as a mid-point a lot, for example.

    One I had noticed with the introduction of DTW-GRU is that NRT-DTW-GRU clocks in at 9986, where NRT-GRU is 9984. Two miles off for a distance of almost 10K miles is pretty amazing, especially as this is probably one of the best connections available between those pairs.

    We got very close last year with DCA-DTW-ICN – fewer than 100 miles longer than IAD-ICN nonstop. It was going to be an award ticket either way, and given that the connection was in business and the nonstop was economy, those extra 80 or so miles plus a bit of ground time weren’t a bad trade-off.

    How’s this one for perfection? This was my most common work commute in 2016 and 2017. Of course, I had to fly it with the connection – it doesn’t exist as a nonstop on any airline.

    In other words, connections to avoid. If I’m going to go through the hassle of connecting, I darn well better be earning extra miles! 😉

    Interesting that you chose ARN-PMI as an example with FRA as a stopover. I flew ARN-PMI last year and the route took us west over Denmark, then south over Hamburg and Luxembourg, then over the south of France and into Palma. Got me wondering if a 1-stop via FRA might actually be shorter in real life?

    Very interesting but I put the more weight on the properties of the connecting airport.

    1. Decent IROPS possibilities? ORD is better than MKE in this regard.
    2. Red eye considerations. For example, if flying from PDX to Europe, a connection in SEA or SFO may allow more sleep than JFK or BOS.
    3. Weather. An ORD connection is riskier in the winter than DFW or DEN.

    MFR-ATL is 2,163 miles. Fly United and connect in DEN and it comes to exactly 2,163. Fly Delta and connect in SLC and it’s a whopping 2,164 miles. So the two places you would most likely connect on that trip are perfect and 1 mile off perfect.

    ORD-SFO vs a stop in DEN is a 9 mi difference.

    How good are the lounges?
    How delay prone? Weather and ATC
    Save money?
    Way more important than whether it is on the great circle
