Not all airlines hand out peanuts on a flight, but many of them might be handing back refunds.
Last weekend, airlines stopped charging certain federal airline ticket taxes when Congress failed to reauthorize a bill to fund the Federal Aviation Administration.
The taxes were charged on domestic and foreign tickets and included cargo and excise taxes.
But if you bought a ticket, paid those taxes and traveled this week, the Internal Revenue Service says the airlines could owe you a tax refund.
On a $300 domestic ticket, the refund could be around $30. A more expensive ticket means more of a refund.
But the refund process is causing confusion.
The IRS is telling passengers to call their airline for the refund.
Dallas-based Southwest Airlines is telling passengers to call the IRS because the government already received the tax money. And Fort Worth-based American Airlines wants more direction from the IRS before moving forward.
Travel experts are advising passengers to keep all their airplane ticket receipts until more details come out.
