I don't fit
One of the metrics used in this report was complaints per 100,000 passengers. Southwest airlines had the fewest; United and US Airways had the most according to this report. I'm going to make a bold statement here: I believe that we are not complaining enough. (I know it is rare that Americans could be so accused!) Airlines claim to listen to their customers. If you want your voice heard, it seems like a good start to actually speak!
I have a particular axe to grind here. At 6 foot 7 inches tall, I'm
far beyond anything "typical". Below is a chart I lifted from
here which illustrates this nicely.
The 50th percentile, the thick red line, delineates the point where half of men will be taller than this height and half of men will be shorter. Similarly, the 75th percentile line shows the height where only a quarter of men are taller and three quarters are shorter.
Life out at the 3 standard deviation point is interesting enough in any day-to-day activity, but it gets especially interesting when getting on an airliner.
On the last set of flights the seat pitch was so short that I had to sit diagonally in my seat for the cross country flight because my legs were too long. Scoff as you will at the person too fat for the seat, but I could diet from now until the cows come home and my legs won't get any shorter. Granted, I'm off the scale (as per the above diagram) but the fellow sitting next to me on that last leg of the trip was only about 6 foot tall and he fit in his seat with only about an inch to spare. That's the 75th percentile point on that graph.
My Seattle trip included four flights on American Airlines MD80/83 airplanes. BOS to DFW (flight 1113), DFW to SEA (1587), and returning with SEA to ORD (1956), and ORD to BOS (874). Each of these airplanes seat about 142 people in two classes (coach and business). If American is arranging these seats to accommodate the 75th or 85th percentile, then a full 15% of the passengers (perhaps 20 people per flight) are uncomfortable. Several, like me, probably didn't fit in their seat at all. Nobody (I hope) had as much trouble as I had.
I just measured myself from the back of the seat to the end of my knees. That distance is about 28.5 inches. On these flights, the coach seats had something approximating 27 or even 26 inches. I sat diagonally coast-to-coast on every flight but one (when I managed to get the exit row... by begging).
I'm never taking these flights again. I'll never fly on an MD80 again if I can help it. I'm also thinking about writing to American Airlines. If I can sit comfortably on a Southwest flight, why can I not find an AA flight with reasonable seating? Again, airlines claim to listen to their customers. We'll see.
