摘要

Abstract

This study examines how fleet modernization

specifically integrating the Airbus A350

affects airline profitability and operational efficiency amidst growing macroeconomic uncertainty. Using a 15-year longitudinal panel dataset of five major Asian carriers

we estimate fixed-effects regression models to evaluate the aircraft's impact on unit costs (CASM) and unit revenues (RASM). Our results show that while the A350 carries high initial capital costs

it significantly reduces CASM once passenger load factors exceed a critical threshold of 84.2%. Notably

during the post-pandemic period of elevated fuel prices

the aircraft functioned as a crucial "physical hedge" against cost inflation. On the revenue side

the A350 drove abnormal yield premiums during the pandemic due to its superior belly-cargo capacity

a revenue advantage that persisted into the post-pandemic recovery. We conclude that adopting versatile

fuel-efficient widebody aircraft is a fundamental strategy for maintaining financial resilience in volatile aviation markets.
