To compare the fleet age and evaluate which airline has the newer planes between United Airlines and Delta Air Lines, we first look at the relevant data on United Airlines.

According to multiple sources, United Airlines recently reported an average fleet age of approximately 15.9 to 16.4 years as of March 2025. The airline possesses a fleet of 1,015 aircraft, with plans to retire 21 older planes within the year and further deliveries planned until 2032, starting in January 2026. This indicates a proactive approach to updating their fleet and improving service quality (source: Planespotters.net, Wikipedia, Simple Flying).

Now, it is crucial to compare this with Delta Air Lines. However, additional data about Delta's fleet age was not included in the current search results.

To determine which airline has newer planes and which one might be considered better, we require an assessment of Delta's average fleet age, which could ideally focus on specific metrics such as passenger comfort, service quality, and fleet management practices in conjunction with fleet age.

In conclusion, while United Airlines has a maximum average fleet age of around 16.4 years and is making efforts to update their aircraft, further information regarding Delta's fleet age and key performance indicators is necessary for a fair comparison. Without this data, a definitive answer on which airline is "better" based on newer planes cannot be provided.
