How to Tell If You're Flying on a Boeing 737 MAX in North America

The Boeing 737 MAX is the latest generation in the 52-year storied history of the Boeing 737. While it's hailed by Boeing as a game-changer for airlines in reliability, efficiency and passenger comfort, two crashes of the new aircraft type in the past five months are causing passengers — and some flight attendants — to wonder about the safety of the new aircraft type.

While Beijing has asked Chinese airlines to ground all 737 MAX aircraft as of Sunday night, US carriers are yet to follow suit. So, we looked at the largest operators of the Boeing 737 MAX here in North America to see what options passengers have in response to multiple TPG readers having reached out to ask what can be done if they're booked on a Boeing 737 MAX flight. The airlines told us that they stand behind the aircraft's safety but plan to monitor the investigation into Sunday's Ethiopian Airlines crash.

Update: The Boeing 737 MAX has now been grounded in the US

And Lori Bassani, president of the Association of Professional Flight Attendants, which represents the cabin crews at American Airlines, said "this event has raised safety concerns" for her members. The union is currently in a contract dispute with the airline.

The nation's largest pilots' union, however, asked passengers to let the investigators do their work before jumping to conclusions. "We caution against speculation about what may have caused this tragic accident," the Air Line Pilots Association said in a statement.

Airlines generally won't let passengers change flights because of fears over what aircraft they are on without paying a hefty fee. However, you can avoid booking new flights on this jet type, if you are concerned.

But before we get to that, here's a quick look at the largest Boeing 737 MAX operators today, according to AirFleets and their current status:

Southwest

Southwest was supposed to be the launch customer of the 737 MAX, but ended up having to settle for being the first North American operator of the new aircraft type. Southwest has safely operated the 737 MAX since its first flights in October 2017 and currently operates a fleet of 34 Boeing 737 MAX 8.

Southwest said in a statement that "we have been in contact with Boeing and will continue to stay close to the investigation as it progresses. We remain confident in the safety and airworthiness of our fleet of more than 750 Boeing aircraft." Southwest's entire fleet is made up of different variants of the Boeing 737.

The airline has "not changed any of our policies or restrictions based on this incident."

TPG spoke with long-time airline journalist Seth Kaplan who was able to analyze Southwest scheduling data through Diio Mi. He found that the most common routes that Southwest operates the 737 MAX are currently:

• Las Vegas (LAS) - Houston Hobby (HOU)
• Washington Dulles (IAD) - Denver (DEN)
• Milwaukee (MKE) - Phoenix (PHX)
• Nashville (BNA) - Phoenix (PHX)
• Dallas Love Field (DAL) - Denver (DEN)
• Denver (DEN) - Sacramento (SMF)

American Airlines

The world's largest airline was the second US airline to take delivery of the Boeing 737 MAX and currently operates 24 of the aircraft type. While the aircraft hasn't made many fans due to its dense configuration, it's operated safely for American Airlines since its inaugural flight in November 2017.

Shortly after the Lion Air crash, the airline released a statement that it has "not had similar issues regarding an erroneous Angle of Attack during manual flight." On follow-up today, the airline confirmed that this is still the case.

Regarding the Ethiopian Airlines crash, American Airlines has provided the following statement to TPG:

American Airlines extends our condolences to the families and friends of those on board Ethiopian Airlines flight 302. At this time there are no facts on the cause of the accident other than news reports. Our Flight, Flight Service, Tech Ops and Safety teams, along with the Allied Pilots Association (APA) and Association of Professional Flight Attendants (APFA), will closely monitor the investigation in Ethiopia, which is our standard protocol for any aircraft accident. American continues to collaborate with the FAA and other regulatory authorities, as the safety of our team members and customers is our number one priority. We have full confidence in the aircraft and our crew members, who are the best and most experienced in the industry.

For passengers that are adamant about avoiding the MAX, here Kaplan also analyzed American Airlines scheduling data through Diio Mi for TPG. The most common current routes are:

• Miami (MIA) - New York LaGuardia (LGA)
• Miami (MIA) - Boston (BOS)
• Miami (MIA) - Bridgetown, Barbados (BGI)
