Late to the party but I'm flying a 737-900 next week. I was concerned, so I looked up if its the "plane", turns out, it is not. Boeing naming is so confusing.

Late to the party but I'm flying a 737-900 next week. I was concerned, so I looked up if its the "plane", turns out, it is not. Boeing naming is so confusing. 737 naming: [1] The first generation "Original" series: the 737-100 and -200, also the military T-43 and CT-43, launched February 1965. [2] The second generation "Classic" series: 737-300, -400 and -500, launched in 1979. [3] The third generation "Next Generation" series: 737-600, -700, -800 and -900, also the military C-40 and P-8, launched late 1993. [4] The fourth generation 737 MAX series: 737-7, -8, -9 and -10, launched August 2011. I read a funny quote from a pilot today, "737, flying yesterday's plane tomorrow".
