American Airlines is one of the most popular airlines in the world. It is the largest global airline in terms of passengers carried and in terms of daily flights. Over the years, the airline has remained relevant in the commercial aviation industry due to its increasing network of routes and modernization of its aircraft fleet. Alongside the addition of new aircraft, the airline has also undergone significant transformations in the design and functionality of its interior cabins. These changes reflect broader shifts in passenger expectations, technology, and cost-efficiency strategies.
