Note: SIFL Rates are determined and issued by the U.S. Department of Transportation for every six-month period. Because of the methodology used in calculations, new rates are often published six-to-eight weeks into each new period. NBAA will update these SIFL rates as soon as they are available.
COVID-19 Update
March 12, 2021
SIFL rates are calculated by the U.S. DOT using airline cost and seat mile data. Due to the unprecedented reduction in airline seat miles because of the COVID-19 pandemic, SIFL rates for this period increased significantly.
DOT also published alternative rates that take into account government relief received by the major airlines. Review the alternative rates.
NBAA has asked the IRS if they plan to accept these lower alternative rates and is awaiting a response.
