Triangle Trip

While the answer should be “direct flights only,” sometimes work sends us to places where we don’t have the luxury of options.  I’ve become an avid user of Hipmunk when it comes to booking complex travel, but have run across issues with what they deem to be appropriate layover windows.

While Detroit (DTW) is a perfectly fine airport and getting from gate A1 to A77 is a surprisingly easy affair when utilizing the indoor tram, getting from Concourse A to Concourse C requires no less than several sherpas and a dune buggy.  On a recent layover (connections on the same airline) I had 32 minutes to get from an A gate to a C gate.  Only for the providence of a flight delay did I make my flight.

So I have three questions for this community:

1. Can flight aggregators better predict sufficient layover times based on historical gate placement of flights?

2. What is generally the right time threshold for a layover?  45 min?

3. What airports are your personal torments when it comes to bad layovers?  (ORD, LAX and ATL are too obvious)
