A video demonstrating the Steffen Method has been going viral on Reddit for years, periodically resurfacing in the r/interestingasf**k subreddit with the same comment section: why are airlines so incompetent that they still board back-to-front when science has definitively proven a better way? The Steffen Method boards window seats in alternating rows first, 30A, then 28A, then 26A, then mirrors on the other side, then odd rows, then middle seats, then aisle seats. In controlled field tests it proved nearly twice as fast as conventional boarding and 20 to 30 percent faster than random free-for-all boarding.
Airlines know about the Steffen Method. They have studied it extensively. Former American Airlines CEO Doug Parker explained why it does not work at an internal company meeting: "We've studied this with operations engineers who go look and watch and we don't see any material change." The gap between the lab result and the real-world result comes down to four things the Steffen Method assumes away.
First: not everyone is at the gate when their boarding group is called. People are getting food, stuck at security, or just arrived off a late connection. The mathematically optimal sequence requires everyone to board in precise order. Real boarding does not work that way. Second: passengers get back up after they sit down, to help someone with a bag, to use the lavatory, to switch seats. Each person re-entering the aisle creates a jam that the Steffen model does not account for. Third: the method separates families. A two-year-old in 28A does not board before their parent in 28C without someone supervising the child. Fourth and most importantly for airlines: boarding order is a revenue tool. Frequent flyers and co-brand credit card holders board early as a benefit, and that benefit drives credit card acquisition. Southwest estimated that adding even a couple of minutes of block time to each flight would cost the equivalent of 8 to 10 aircraft per day across its network.
The boarding process is slow because the incentives that would make it faster, free checked bags reducing carry-on volume, random seat assignment encouraging early gate arrival, uniform boarding order regardless of status, conflict with the revenue structures airlines have built around the boarding door. The Steffen Method is faster in a laboratory. The laboratory does not have a co-brand credit card product.
