WN2660: MEM → HOU – Flight Guide

The Boeing 737 Classic series (737-300/400/500) is one of the most experienced aircraft types in commercial aviation, having accumulated hundreds of millions of flight hours since the 1980s. It is certified to rigorous standards and maintained meticulously by operators worldwide.

The original Boeing 737 first flew in 1967 and entered service in 1968, making it the longest-running commercial jet program in history. The Classic series (300/400/500) introduced in the 1980s was a major upgrade with new CFM56 engines. The design has been continuously developed through subsequent generations.

The 737-300 seats 128-149 passengers, the 737-400 seats 147-168, and the 737-500 seats 108-132, all in a 3-3 economy layout. The narrower cabin means seats are slightly tighter than on the A320 family.

The 737 Classic is a competent short-haul aircraft for flights under 3-4 hours. The 3-3 economy layout means a centre seat is always in the middle section, which can feel tight on busy flights. Exit rows and front rows are the most comfortable options.

The 737 Classic has a distinct engine sound from its CFM56 engines. It is louder than more modern aircraft like the A320neo or 737 MAX, particularly at the rear of the cabin. Front rows and seats over the wing are quieter.

Exit rows provide the most legroom. Front rows (1-5) are quietest and allow faster disembarkation. Window seats in rows 10-15 over the wing experience the least turbulence. Avoid the last 5 rows — they are the loudest and may have non-reclining seats.

The 737 Classic is becoming less common as airlines retire older jets, but it can still be found with some smaller European carriers, leisure airlines, and operators in developing markets. Many have been replaced by the 737-800 and 737 MAX.

The A320 has a slightly wider cabin (3.7m vs 3.53m), which makes seats marginally wider. The A320 uses fly-by-wire technology which the 737 Classic does not. However, both are proven short-haul jets and the passenger experience is similar.

Yes, the 737 Classic is a very proven and reliable aircraft. While it is older than modern jets, it has accumulated decades of reliable service. Its familiarity and strong track record can be reassuring for nervous flyers.

The 737 Classic typically has 2 toilets: one at the front and one at the rear. On short flights this is usually adequate, though queues can form at the rear on full flights during the descent.

Most 737 Classic operations do not include Wi-Fi, as the aircraft type is older and generally operated by airlines that have not invested in connectivity retrofits. Exceptions may exist on some carriers.

The 737-300/400/500 have ranges between 2,500 and 5,000 km depending on variant. They are designed for short to medium-haul routes, typically under 4 hours.

The 737 Classic has older, smaller overhead bins compared to modern aircraft. On full flights, bin space can run out quickly. Checking your bag or boarding early is recommended to secure space near your seat.

Landings are generally smooth, with the quality depending primarily on the pilot and weather conditions. The 737 Classic has robust landing gear and well-proven approach characteristics.

Yes, the 737 Classic series is gradually being retired across the industry as airlines replace them with more fuel-efficient modern aircraft like the 737-800, 737 MAX, and A320neo. However, many will remain in service for years to come with smaller operators.
