11/29 is used mainly for short-range turboprop and RJ services. 737's use it sparingly for landings only from close-in cities. Personally, I think the approach to 11/29 is nicer than 4 L/R or 22 L/R, but I haven't flown it in years. In fact, I think the last time I was on it was in a 727 from Manchester, NH in 1991. 4R/22L gets 85% of all landing traffic, while 4L/22R gets 99% of takeoff traffic. Of course, the remaining 15% of landings and 1% of takeoffs funnel through 11/29.
