Methodology for Determining Change in Operating Expense (SIFL) - Alternative 1

About this Document:  Alternative 1 - SIFL Rates Adjusted for PSP Grants

The Department of Transportation has continued to calculate the Standard Industry Fare Level (SIFL) adjustment factor to aid in its evaluation of carrier pricing in the free market.  The SIFL is also used by the Internal Revenue Service in imputing the value of free transportation provided on corporate aircraft.

Rates Adjusted for PSP Grants– This reduces industry expenses by the amount of PSP Grants provided to the SIFL carriers; adjustments do not factor in promissory notes or warrants issued as part of the PSP.
