Navigating the Skies: Understanding the Boeing 737 Family and Which Models Might Give You Pause
As a frequent flyer, or even an occasional one, you've likely been on a Boeing 737. It's the workhorse of many airline fleets, a staple of short- and medium-haul routes across the United States and the globe. But with the recent high-profile incidents involving the 737 MAX, many travelers are understandably asking: "Which Boeing 737 should I avoid?" This article aims to provide a clear, detailed, and specific answer for the average American reader, delving into the nuances of the 737 family.
The Boeing 737: A Long and Storied History
The Boeing 737 has been in production since the late 1960s. Over its decades-long history, it has undergone significant evolution, leading to different "generations" of the aircraft. Understanding these generations is key to understanding which models might be considered more or less concerning.
The Original (or "Whisperjet") Generation (737-100/-200)
These were the first 737s to take to the skies. While they served reliably for many years, they are now largely retired from major airline service. You're unlikely to encounter these on your typical commercial flight, but if you do, it would likely be on a very niche or cargo operation. They are characterized by their smaller size and older technology.
The Classic Generation (737-300/-400/-500)
Introduced in the early 1980s, the "Classic" 737s were a significant upgrade. They featured new engines, updated avionics, and a longer fuselage on some variants. These aircraft are still in service with some smaller airlines or for charter operations, but many have been phased out by larger carriers in favor of newer models. They are generally considered safe, but are a generation behind the latest technology.
The Next-Generation (NG) Series (737-600/-700/-800/-900/-900ER)
This is where things get interesting for the average traveler. The Next-Generation (NG) series, launched in the mid-1990s, represents a massive leap in efficiency and performance. The 737-800 and 737-900ER are incredibly common on U.S. domestic routes, operated by nearly every major airline. These aircraft are reliable, well-maintained, and have an excellent safety record. There is generally no reason for the average traveler to "avoid" a 737 NG.
However, it's important to note that the 737 NG series is the direct predecessor to the 737 MAX. Some of the design philosophies and underlying systems, while heavily revised for the MAX, can be traced back to the NG.
The 737 MAX Series (737-7/-8/-9/-10)
This is the generation that has garnered the most attention and concern. The 737 MAX was designed to be the most fuel-efficient iteration of the 737. It features larger, more powerful engines that are positioned differently on the wing compared to previous 737s. This change in engine placement led to aerodynamic characteristics that required a new flight control software system, known as the Maneuvering Characteristics Augmentation System (MCAS).
It is the MCAS system that has been at the center of two tragic accidents: Lion Air Flight 610 in October 2018 and Ethiopian Airlines Flight 302 in March 2019. These accidents, which resulted in the loss of all 346 people on board, led to the global grounding of the 737 MAX fleet for nearly two years.
Following the grounding, Boeing implemented significant software and training fixes to address the issues with MCAS. The aircraft has since been recertified by aviation authorities in the United States (FAA) and other countries. Major U.S. airlines have resumed flying the 737 MAX.
So, Which Boeing 737 Should You Avoid?
For the average American traveler, the answer is nuanced and depends on what you mean by "avoid."
If you are looking for the safest and most technologically advanced 737, you might prefer the newer MAX models (once all the kinks have been ironed out and trust is fully restored). However, this is a personal decision based on your comfort level.
If you are concerned about the most recent controversies and the design flaws that led to the MAX accidents, you might choose to avoid the 737 MAX series (737-7, 737-8, 737-9, 737-10). This is a valid personal choice. Many travelers who are still wary have successfully avoided flying on the MAX by checking their flight details.
You generally do not need to worry about avoiding the older generations:
- The Original (-100/-200) are rarely in commercial service.
- The Classic (-300/-400/-500) are also becoming less common and are not typically flown by major U.S. carriers for passenger service.
- The Next-Generation (NG) series (-600/-700/-800/-900/-900ER) are extremely common and have a proven track record of safety. There is no widespread reason to avoid these aircraft.
How to Know What You're Flying On
Airlines are required to disclose the aircraft type for your flight. Here's how you can typically find out:
- When Booking: Most airline websites will display the aircraft type next to the flight details during the booking process.
- After Booking: Once you have booked your flight, you can usually find the aircraft type in your reservation details on the airline's website or app.
- Third-Party Websites: Many travel booking sites (like Google Flights, Kayak, Expedia) also show the aircraft type.
- Flight Tracking Apps: Apps like FlightAware or FlightRadar24 allow you to track your specific flight and see the aircraft registration and model.
Our Recommendation for the Average Traveler
The vast majority of Boeing 737s you will encounter are the Next-Generation (NG) series, particularly the 737-800 and 737-900ER. These are safe, reliable aircraft. The 737 MAX series has undergone extensive scrutiny and modifications, and regulatory bodies have deemed it safe to fly. Therefore, the decision to avoid the 737 MAX is largely a matter of personal comfort and trust.
If you are uncomfortable flying on the 737 MAX, you can actively check your flight details and rebook if necessary. For most travelers, the 737 NG series is an excellent and safe option, and there's no compelling reason to avoid it.
Frequently Asked Questions (FAQ)
How can I check if my flight is on a Boeing 737 MAX?
You can typically check the aircraft type for your flight on the airline's website or app after you book. Many third-party travel booking sites also display this information. If you're still unsure, you can often use flight tracking websites or apps to identify the specific aircraft by its tail number.
Why were the Boeing 737 MAX planes grounded?
The 737 MAX planes were grounded globally due to two fatal accidents: Lion Air Flight 610 and Ethiopian Airlines Flight 302. Investigations revealed that a new flight control software system called MCAS played a role in both crashes, due to design flaws and pilots not being adequately trained on how to handle it.
Are the newer Boeing 737s safe to fly?
Following the grounding and extensive investigations, Boeing made significant modifications to the MCAS software and provided enhanced pilot training. Aviation regulatory bodies, including the FAA in the United States, have recertified the 737 MAX, deeming it safe to fly after these changes were implemented. However, individual comfort levels with the aircraft may vary.
What's the difference between a Boeing 737 NG and a 737 MAX?
The 737 MAX is the latest generation of the 737 family. It features larger, more fuel-efficient engines that are positioned differently on the wing, leading to aerodynamic changes. To compensate for these changes, the MAX introduced the MCAS software, which was the source of the earlier safety concerns. The NG series, while older, does not have the MCAS system.
