American Airlines Group AAL is scheduled to report fourth-quarter 2021 results on Jan 20, before market open.The Zacks Consensus Estimate for fourth-quarter loss has widened by 3.5% in the past 60 days. Given this, let’s take a look at the factors that are expected to have influenced the company’s fourth-quarter performance:With improved air-travel demand, American Airlines’ passenger revenues are expected to reflect sequential increase in the fourth quarter. The Zacks Consensus Estimate for fourth-quarter passenger revenues indicates a 1.1% rise from the third-quarter reported number. Robust Thanksgiving holiday demand is expected to have boosted the carrier’s passenger revenues.However, mass-scale flight cancellations between late October and early November, as well as during the Christmas travel period through the end of the year owing to staffing shortages and inclement weather conditions, pushed up American Airlines’ costs. The airline expects cost per available seat mile (“CASM”) to increase 13-14% in the fourth quarter from the 2019 level. Apart from reduced capacity, a holiday operational incentive program in the fourth quarter and a write down of excess spare-parts inventory pushed up the company’s unit costs. The higher expenses are likely to have hurt AAL’s bottom line in the to-be-reported quarter.Rising fuel costs are also expected to have dented American Airlines’ bottom line in the fourth quarter. American Airlines estimates average fuel price per gallon to be $2.36 for the fourth quarter, indicating a rise of 14% from the third quarter’s reported figure. The Zacks Consensus Estimate for the same stands at $2.42.Despite improving, air-travel demand continues to be below the pre-pandemic levels. As a result, American Airlines expects total revenues to decline approximately 17% in the fourth quarter of 2021 from the comparable period in 2019.American Airlines Group Inc.
