It’s bad news for United Airlines in their attempts to secure the services of the high-capacity 737 MAX model, the 737-10.
In fresh reporting, the uncertainty surrounding the delivery timeframe of the next-generation and largest MAX variant remains all the more unclear, and United Airlines is now preparing for the worst-case scenario.
As part of fresh estimates, United Airlines may not welcome the 737-10 unit in 2027, or even most likely in 2028, given the complexities in the certification of this aircraft type, which was meant to enter service years ago.
The U.S. carrier’s frustrations with the MAX have been evident recently, with adjustments required to the fleet makeup and a heavier reliance on approved jets within the series.
United Airlines Struggles With The 737 MAX
While the 737 MAX remains a mainstay in the global aircraft fleet, onlookers would be forgiven for sometimes forgetting that there are still two unapproved aircraft types in the broader series.
Worse still, these two aircraft variants have substantial commitments and are intended to serve a purpose with airlines; therefore, unlike the A330-800 or upcoming 777-8 which have lacked interest, let alone any firm orders.
In early 2024, United Airlines even reconsidered its order for the 737-10, albeit this decision was based on a door blowout incident that uncovered many struggles still in the Boeing operation.
However, the airline CEO, Scott Kirby, was not unwarranted in his feelings. Analysts believed that the incident at the time was the straw that broke the camel’s back, as the company’s frustrations with the program increased tenfold.
For many reasons, the 737-10 is meant to be a massive part of the carrier’s fleet makeup in an industry where no planemaker proceeded with what many airlines required in a middle-of-the-market airliner. Due to this, the reliance on the 737-10 has increased beyond what may have been imagined many years ago.

Due to complications, United has been forced to look towards Airbus and the A321neo model to try and answer some of the questions it needs to solve. This switch is because Boeing’s inability to get planes certified has prevented United from growing as it would like and needs to.
Like aircraft groundings, one of the biggest challenges remains the uncertainty in acquiring new planes. Boeing has published timeline after timeline, but on each occasion, it has not been able to meet this.
Due to timelines not being met, forecasting renewal, growth, and overall deliveries for airlines such as United has been next to impossible, and this is where more challenges have arisen.
