The 737 Classic follows the original generation of Boeing 737 aircraft, and includes the -300, -400 and -500 variants. It’s becoming increasingly scarce, often now only being operated by some charter airlines or remote cargo carriers. The first variant, the -300, first flew in 1984 and is the medium sized of the three. Most Boeing 737 classic examples can be spotted by a distinct lack of winglets, however this is the same on the Boeing 737-600 as well. Compared to the Boeing 737 NG, the differences are subtle, with the classic series having smaller engines and a smaller vertical stabilizer.
