Delta will provide a tax refund to all travelers who booked a flight before July 23 that departed on or after that date, when Federal Aviation Administration funding officially ran out. Refunding is pending approval from Congress. Since the FAA is responsible in part for collecting taxes from U.S. airlines but is unable to until Congress reauthorizes its funding, carriers no longer need to charge most taxes.
While a few airlines are offering a temporary tax holiday, many including Delta simply jacked up their pretax prices to boost profits. But now the airline is offering some small consolation.
People who did pay taxes on flights that left during this temporary tax holiday because the tickets were booked before FAA funding ran out will be entitled to a modest refund that includes the 7.5% tax on the base ticket price as well as a $3.70 segment tax and, if applicable, international travel taxes. So, for example, if you booked a domestic flight for $300, you could potentially get back at least $25.
